/***************************************************************************** DESCRIPTION ****************************************************************************** Note: the descriptions of the functions are alphabetically arranged. Please maintain the arrangement when adding a new function description. The actual prototypes are below this comment section and donot follow any alphabetical ordering. --------------------------------OCIAttrGet------------------------------------ OCIAttrGet() Name OCI Attribute Get Purpose This call is used to get a particular attribute of a handle. Syntax sword OCIAttrGet ( const void *trgthndlp, ub4 trghndltyp, void *attributep, ub4 *sizep, ub4 attrtype, OCIError *errhp ); Comments This call is used to get a particular attribute of a handle. See Appendix B, "Handle Attributes", for a list of handle types and their readable attributes. Parameters trgthndlp (IN) - is the pointer to a handle type. trghndltyp (IN) - is the handle type. attributep (OUT) - is a pointer to the storage for an attribute value. The attribute value is filled in. sizep (OUT) - is the size of the attribute value. This can be passed in as NULL for most parameters as the size is well known. For text* parameters, a pointer to a ub4 must be passed in to get the length of the string. attrtype (IN) - is the type of attribute. errhp (IN/OUT) - an error handle which can be passed to OCIErrorGet() for diagnostic information in the event of an error. Related Functions OCIAttrSet() --------------------------------OCIAttrSet------------------------------------ OCIAttrSet() Name OCI Attribute Set Purpose This call is used to set a particular attribute of a handle or a descriptor. Syntax sword OCIAttrSet ( void *trgthndlp, ub4 trghndltyp, void *attributep, ub4 size, ub4 attrtype, OCIError *errhp ); Comments This call is used to set a particular attribute of a handle or a descriptor. See Appendix B for a list of handle types and their writeable attributes. Parameters trghndlp (IN/OUT) - the pointer to a handle type whose attribute gets modified. trghndltyp (IN/OUT) - is the handle type. attributep (IN) - a pointer to an attribute value. The attribute value is copied into the target handle. If the attribute value is a pointer, then only the pointer is copied, not the contents of the pointer. size (IN) - is the size of an attribute value. This can be passed in as 0 for most attributes as the size is already known by the OCI library. For text* attributes, a ub4 must be passed in set to the length of the string. attrtype (IN) - the type of attribute being set. errhp (IN/OUT) - an error handle which can be passed to OCIErrorGet() for diagnostic information in the event of an error. Related Functions OCIAttrGet() --------------------------------OCIBindArrayOfStruct-------------------------- OCIBindArrayOfStruct() Name OCI Bind for Array of Structures Purpose This call sets up the skip parameters for a static array bind. Syntax sword OCIBindArrayOfStruct ( OCIBind *bindp, OCIError *errhp, ub4 pvskip, ub4 indskip, ub4 alskip, ub4 rcskip ); Comments This call sets up the skip parameters necessary for a static array bind. This call follows a call to OCIBindByName() or OCIBindByPos(). The bind handle returned by that initial bind call is used as a parameter for the OCIBindArrayOfStruct() call. For information about skip parameters, see the section "Arrays of Structures" on page 4-16. Parameters bindp (IN) - the handle to a bind structure. errhp (IN) - an error handle which can be passed to OCIErrorGet() for diagnostic information in the event of an error. pvskip (IN) - skip parameter for the next data value. indskip (IN) - skip parameter for the next indicator value or structure. alskip (IN) - skip parameter for the next actual length value. rcskip (IN) - skip parameter for the next column-level return code value. Related Functions OCIAttrGet() --------------------------------OCIBindByName--------------------------------- OCIBindByName() Name OCI Bind by Name Purpose Creates an association between a program variable and a placeholder in a SQL statement or PL/SQL block. Syntax sword OCIBindByName ( OCIStmt *stmtp, OCIBind **bindp, OCIError *errhp, const OraText *placeholder, sb4 placeh_len, void *valuep, sb4 value_sz, ub2 dty, void *indp, ub2 *alenp, ub2 *rcodep, ub4 maxarr_len, ub4 *curelep, ub4 mode ); Description This call is used to perform a basic bind operation. The bind creates an association between the address of a program variable and a placeholder in a SQL statement or PL/SQL block. The bind call also specifies the type of data which is being bound, and may also indicate the method by which data will be provided at runtime. This function also implicitly allocates the bind handle indicated by the bindp parameter. Data in an OCI application can be bound to placeholders statically or dynamically. Binding is static when all the IN bind data and the OUT bind buffers are well-defined just before the execute. Binding is dynamic when the IN bind data and the OUT bind buffers are provided by the application on demand at execute time to the client library. Dynamic binding is indicated by setting the mode parameter of this call to OCI_DATA_AT_EXEC. Related Functions: For more information about dynamic binding, see the section "Runtime Data Allocation and Piecewise Operations" on page 5-16. Both OCIBindByName() and OCIBindByPos() take as a parameter a bind handle, which is implicitly allocated by the bind call A separate bind handle is allocated for each placeholder the application is binding. Additional bind calls may be required to specify particular attributes necessary when binding certain data types or handling input data in certain ways: If arrays of structures are being utilized, OCIBindArrayOfStruct() must be called to set up the necessary skip parameters. If data is being provided dynamically at runtime, and the application will be using user-defined callback functions, OCIBindDynamic() must be called to register the callbacks. If a named data type is being bound, OCIBindObject() must be called to specify additional necessary information. Parameters stmth (IN/OUT) - the statement handle to the SQL or PL/SQL statement being processed. bindp (IN/OUT) - a pointer to a pointer to a bind handle which is implicitly allocated by this call. The bind handle maintains all the bind information for this particular input value. The handle is feed implicitly when the statement handle is deallocated. errhp (IN/OUT) - an error handle which can be passed to OCIErrorGet() for diagnostic information in the event of an error. placeholder (IN) - the placeholder attributes are specified by name if ocibindn() is being called. placeh_len (IN) - the length of the placeholder name specified in placeholder. valuep (IN/OUT) - a pointer to a data value or an array of data values of the type specified in the dty parameter. An array of data values can be specified for mapping into a PL/SQL table or for providing data for SQL multiple-row operations. When an array of bind values is provided, this is called an array bind in OCI terms. Additional attributes of the array bind (not bind to a column of ARRAY type) are set up in OCIBindArrayOfStruct() call. For a REF, named data type bind, the valuep parameter is used only for IN bind data. The pointers to OUT buffers are set in the pgvpp parameter initialized by OCIBindObject(). For named data type and REF binds, the bind values are unpickled into the Object Cache. The OCI object navigational calls can then be used to navigate the objects and the refs in the Object Cache. If the OCI_DATA_AT_EXEC mode is specified in the mode parameter, valuep is ignored for all data types. OCIBindArrayOfStruct() cannot be used and OCIBindDynamic() must be invoked to provide callback functions if desired. value_sz (IN) - the size of a data value. In the case of an array bind, this is the maximum size of any element possible with the actual sizes being specified in the alenp parameter. If the OCI_DATA_AT_EXEC mode is specified, valuesz defines the maximum size of the data that can be ever provided at runtime for data types other than named data types or REFs. dty (IN) - the data type of the value(s) being bound. Named data types (SQLT_NTY) and REFs (SQLT_REF) are valid only if the application has been initialized in object mode. For named data types, or REFs, additional calls must be made with the bind handle to set up the datatype-specific attributes. indp (IN/OUT) - pointer to an indicator variable or array. For scalar data types, this is a pointer to sb2 or an array of sb2s. For named data types, this pointer is ignored and the actual pointer to the indicator structure or an array of indicator structures is initialized by OCIBindObject(). Ignored for dynamic binds. See the section "Indicator Variables" on page 2-43 for more information about indicator variables. alenp (IN/OUT) - pointer to array of actual lengths of array elements. Each element in alenp is the length of the data in the corresponding element in the bind value array before and after the execute. This parameter is ignored for dynamic binds. rcodep (OUT) - pointer to array of column level return codes. This parameter is ignored for dynamic binds. maxarr_len (IN) - the maximum possible number of elements of type dty in a PL/SQL binds. This parameter is not required for non-PL/SQL binds. If maxarr_len is non-zero, then either OCIBindDynamic() or OCIBindArrayOfStruct() can be invoked to set up additional bind attributes. curelep(IN/OUT) - a pointer to the actual number of elements. This parameter is only required for PL/SQL binds. mode (IN) - the valid modes for this parameter are: OCI_DEFAULT. This is default mode. OCI_DATA_AT_EXEC. When this mode is selected, the value_sz parameter defines the maximum size of the data that can be ever provided at runtime. The application must be ready to provide the OCI library runtime IN data buffers at any time and any number of times. Runtime data is provided in one of the two ways: callbacks using a user-defined function which must be registered with a subsequent call to OCIBindDynamic(). a polling mechanism using calls supplied by the OCI. This mode is assumed if no callbacks are defined. For more information about using the OCI_DATA_AT_EXEC mode, see the section "Runtime Data Allocation and Piecewise Operations" on page 5-16. When the allocated buffers are not required any more, they should be freed by the client. Related Functions OCIBindDynamic(), OCIBindObject(), OCIBindArrayOfStruct(), OCIAttrGet() -------------------------------OCIBindByPos----------------------------------- OCIBindByPos() Name OCI Bind by Position Purpose Creates an association between a program variable and a placeholder in a SQL statement or PL/SQL block. Syntax sword OCIBindByPos ( OCIStmt *stmtp, OCIBind **bindp, OCIError *errhp, ub4 position, void *valuep, sb4 value_sz, ub2 dty, void *indp, ub2 *alenp, ub2 *rcodep, ub4 maxarr_len, ub4 *curelep, ub4 mode); Description This call is used to perform a basic bind operation. The bind creates an association between the address of a program variable and a placeholder in a SQL statement or PL/SQL block. The bind call also specifies the type of data which is being bound, and may also indicate the method by which data will be provided at runtime. This function also implicitly allocates the bind handle indicated by the bindp parameter. Data in an OCI application can be bound to placeholders statically or dynamically. Binding is static when all the IN bind data and the OUT bind buffers are well-defined just before the execute. Binding is dynamic when the IN bind data and the OUT bind buffers are provided by the application on demand at execute time to the client library. Dynamic binding is indicated by setting the mode parameter of this call to OCI_DATA_AT_EXEC. Related Functions: For more information about dynamic binding, see the section "Runtime Data Allocation and Piecewise Operations" on page 5-16 Both OCIBindByName() and OCIBindByPos() take as a parameter a bind handle, which is implicitly allocated by the bind call A separate bind handle is allocated for each placeholder the application is binding. Additional bind calls may be required to specify particular attributes necessary when binding certain data types or handling input data in certain ways: If arrays of structures are being utilized, OCIBindArrayOfStruct() must be called to set up the necessary skip parameters.

Parameters stmth (IN/OUT) - the statement handle to the SQL or PL/SQL statement being processed. bindp (IN/OUT) - a pointer to a pointer to a bind handle which is implicitly allocated by this call. The bind handle maintains all the bind information for this particular input value. The handle is feed implicitly when the statement handle is deallocated. errhp (IN/OUT) - an error handle which can be passed to OCIErrorGet() for diagnostic information in the event of an error. position (IN) - the placeholder attributes are specified by position if ocibindp() is being called. valuep (IN/OUT) - a pointer to a data value or an array of data values of the type specified in the dty parameter. An array of data values can be specified for mapping into a PL/SQL table or for providing data for SQL multiple-row operations. When an array of bind values is provided, this is called an array bind in OCI terms. Additional attributes of the array bind (not bind to a column of ARRAY type) are set up in OCIBindArrayOfStruct() call. For a REF, named data type bind, the valuep parameter is used only for IN bind data. The pointers to OUT buffers are set in the pgvpp parameter initialized by OCIBindObject(). For named data type and REF binds, the bind values are unpickled into the Object Cache. The OCI object navigational calls can then be used to navigate the objects and the refs in the Object Cache. If the OCI_DATA_AT_EXEC mode is specified in the mode parameter, valuep is ignored for all data types. OCIBindArrayOfStruct() cannot be used and OCIBindDynamic() must be invoked to provide callback functions if desired. value_sz (IN) - the size of a data value. In the case of an array bind, this is the maximum size of any element possible with the actual sizes being specified in the alenp parameter. If the OCI_DATA_AT_EXEC mode is specified, valuesz defines the maximum size of the data that can be ever provided at runtime for data types other than named data types or REFs. dty (IN) - the data type of the value(s) being bound. Named data types (SQLT_NTY) and REFs (SQLT_REF) are valid only if the application has been initialized in object mode.

For scalar data types, this is a pointer to sb2 or an array of sb2s. For named data types, this pointer is ignored and the actual pointer to the indicator structure or an array of indicator structures is initialized by OCIBindObject(). Ignored for dynamic binds. See the section "Indicator Variables" on page 2-43 for more information about indicator variables. alenp (IN/OUT) - pointer to array of actual lengths of array elements. Each element in alenp is the length of the data in the corresponding element in the bind value array before and after the execute. This parameter is ignored for dynamic binds. rcodep (OUT) - pointer to array of column level return codes. This parameter is ignored for dynamic binds. maxarr_len (IN) - the maximum possible number of elements of type dty in a PL/SQL binds. This parameter is not required for non-PL/SQL binds. If maxarr_len is non-zero, then either OCIBindDynamic() or OCIBindArrayOfStruct() can be invoked to set up additional bind attributes. curelep(IN/OUT) - a pointer to the actual number of elements. This parameter is only required for PL/SQL binds. mode (IN) - the valid modes for this parameter are: OCI_DEFAULT. This is default mode. OCI_DATA_AT_EXEC. When this mode is selected, the value_sz parameter defines the maximum size of the data that can be ever provided at runtime. The application must be ready to provide the OCI library runtime IN data buffers at any time and any number of times. Runtime data is provided in one of the two ways: callbacks using a user-defined function which must be registered with a subsequent call to OCIBindDynamic() . a polling mechanism using calls supplied by the OCI. This mode is assumed if no callbacks are defined. For more information about using the OCI_DATA_AT_EXEC mode, see the section "Runtime Data Allocation and Piecewise Operations" on page 5-16.

Syntax sword OCIBindObject ( OCIBind *bindp, OCIError *errhp, const OCIType *type, void **pgvpp, ub4 *pvszsp, void **indpp, ub4 *indszp, ); Comments This function sets up additional attributes which binding a named data type or a REF. An error will be returned if this function is called when the OCI environment has been initialized in non-object mode. This call takes as a paramter a type descriptor object (TDO) of datatype OCIType for the named data type being defined. The TDO can be retrieved with a call to OCITypeByName(). If the OCI_DATA_AT_EXEC mode was specified in ocibindn() or ocibindp(), the pointers to the IN buffers are obtained either using the callback icbfp registered in the OCIBindDynamic() call or by the OCIStmtSetPieceInfo() call. The buffers are dynamically allocated for the OUT data and the pointers to these buffers are returned either by calling ocbfp() registered by the OCIBindDynamic() or by setting the pointer to the buffer in the buffer passed in by OCIStmtSetPieceInfo() called when OCIStmtExecute() returned OCI_NEED_DATA. The memory of these client library- allocated buffers must be freed when not in use anymore by using the OCIObjectFreee() call. Parameters bindp ( IN/OUT) - the bind handle returned by the call to OCIBindByName() or OCIBindByPos(). errhp ( IN/OUT) - an error handle which can be passed to OCIErrorGet() for diagnostic information in the event of an error. type ( IN) - points to the TDO which describes the type of the program variable being bound.

When the bind variable is also an OUT variable, the OUT Named Data Type value or REF is allocated (unpickled) in the Object Cache, and a pointer to the value or REF is returned, At the end of execute, when all OUT values have been received, pgvpp points to an array of pointer(s) to these newly allocated named data types in the object cache. pgvpp is ignored if the OCI_DATA_AT_EXEC mode is set. Then the Named Data Type buffers are requested at runtime. For static array binds, skip factors may be specified using the OCIBindArrayOfStruct() call. The skip factors are used to compute the address of the next pointer to the value, the indicator structure and their sizes. pvszsp ( IN/OUT) - points to the size of the program variable. The size of the named data type is not required on input. For an array, pvszsp is an array of ub4s. On return, for OUT bind variables, this points to size(s) of the Named Data Types and REFs received. pvszsp is ignored if the OCI_DATA_AT_EXEC mode is set. Then the size of the buffer is taken at runtime. indpp ( IN/OUT) - points to a pointer to the program variable buffer containing the parallel indicator structure. For an array, points to an array of pointers. When the bind variable is also an OUT bind variable, memory is allocated in the object cache, to store the unpickled OUT indicator values. At the end of the execute when all OUT values have been received, indpp points to the pointer(s) to these newly allocated indicator structure(s). indpp is ignored if the OCI_DATA_AT_EXEC mode is set. Then the indicator is requested at runtime. indszp ( IN/OUT) - points to the size of the IN indicator structure program variable. For an array, it is an array of sb2s. On return for OUT bind variables, this points to size(s) of the received OUT indicator structures. indszp is ignored if the OCI_DATA_AT_EXEC mode is set.

Related Functions OCIAttrGet() OCIDefineByPos() Name OCI Define By Position Purpose Associates an item in a select-list with the type and output data buffer. Syntax sb4 OCIDefineByPos ( OCIStmt *stmtp, OCIDefine **defnp, OCIError *errhp, ub4 position, void *valuep, sb4 value_sz, ub2 dty, void *indp, ub2 *rlenp, ub2 *rcodep, ub4 mode ); Comments This call defines an output buffer which will receive data retreived from Oracle. The define is a local step which is necessary when a SELECT statement returns data to your OCI application. This call also implicitly allocates the define handle for the select-list item. Defining attributes of a column for a fetch is done in one or more calls. The first call is to OCIDefineByPos(), which defines the minimal attributes required to specify the fetch. This call takes as a parameter a define handle, which must have been previously allocated with a call to OCIHandleAlloc(). Following the call to OCIDefineByPos() additional define calls may be necessary for certain data types or fetch modes: A call to OCIDefineArrayOfStruct() is necessary to set up skip parameters for an array fetch of multiple columns. A call to OCIDefineObject() is necessary to set up the appropriate attributes of a named data type fetch. In this case the data buffer pointer in ocidefn() is ignored. Both OCIDefineArrayOfStruct() and OCIDefineObject() must be called after ocidefn() in order to fetch multiple rows with a column of named data types. For a LOB define, the buffer pointer must be a lob locator of type OCILobLocator , allocated by the OCIDescAlloc() call. LOB locators, and not LOB values, are always returned for a LOB column. LOB values can then be fetched using OCI LOB calls on the fetched locator. For NCHAR (fixed and varying length), the buffer pointer must point to an array of bytes sufficient for holding the required NCHAR characters. Nested table columns are defined and fetched like any other named data type. If the mode parameter is this call is set to OCI_DYNAMIC_FETCH, the client application can fetch data dynamically at runtime. Runtime data can be provided in one of two ways: callbacks using a user-defined function which must be registered with a subsequent call to OCIDefineDynamic(). When the client library needs a buffer to return the fetched data, the callback will be invoked and the runtime buffers provided will return a piece or the whole data. a polling mechanism using calls supplied by the OCI. This mode is assumed if no callbacks are defined. In this case, the fetch call returns the OCI_NEED_DATA error code, and a piecewise polling method is used to provide the data. Related Functions: For more information about using the OCI_DYNAMIC_FETCH mode, see the section "Runtime Data Allocation and Piecewise Operations" on page 5-16 of Volume 1.. For more information about the define step, see the section "Defining" on page 2-30. Parameters stmtp (IN) - a handle to the requested SQL query operation. defnp (IN/OUT) - a pointer to a pointer to a define handle which is implicitly allocated by this call. This handle is used to store the define information for this column. errhp (IN) - an error handle which can be passed to OCIErrorGet() for diagnostic information in the event of an error. position (IN) - the position of this value in the select list. Positions are 1-based and are numbered from left to right. For example, in the SELECT statement SELECT empno, ssn, mgrno FROM employees; empno is at position 1, ssn is at position 2, and mgrno is at position 3. valuep (IN/OUT) - a pointer to a buffer or an array of buffers of the type specified in the dty parameter. A number of buffers can be specified when results for more than one row are desired in a single fetch call. value_sz (IN) - the size of each valuep buffer in bytes. If the data is stored internally in VARCHAR2 format, the number of characters desired, if different from the buffer size in bytes, may be additionally specified by the using OCIAttrSet(). In an NLS conversion environment, a truncation error will be generated if the number of bytes specified is insufficient to handle the number of characters desired. dty (IN) - the data type. Named data type (SQLT_NTY) and REF (SQLT_REF) are valid only if the environment has been intialized with in object mode. indp - pointer to an indicator variable or array. For scalar data types, pointer to sb2 or an array of sb2s. Ignored for named data types. For named data types, a pointer to a named data type indicator structure or an array of named data type indicator structures is associated by a subsequent OCIDefineObject() call. See the section "Indicator Variables" on page 2-43 for more information about indicator variables. rlenp (IN/OUT) - pointer to array of length of data fetched. Each element in rlenp is the length of the data in the corresponding element in the row after the fetch. rcodep (OUT) - pointer to array of column-level return codes mode (IN) - the valid modes are: OCI_DEFAULT. This is the default mode. OCI_DYNAMIC_FETCH. For applications requiring dynamically allocated data at the time of fetch, this mode must be used. The user may additionally call OCIDefineDynamic() to set up a callback function that will be invoked to receive the dynamically allocated buffers and to set up the memory allocate/free callbacks and the context for the callbacks. valuep and value_sz are ignored in this mode. Related Functions OCIDefineArrayOfStruct(), OCIDefineDynamic(), OCIDefineObject() OCIDefineDynamic() Name OCI Define Dynamic Fetch Attributes Purpose This call is used to set the additional attributes required if the OCI_DYNAMIC_FETCH mode was selected in OCIDefineByPos().

When the OCI_DYNAMIC_FETCH mode is selected, buffers will be dynamically allocated for REF, and named data type, values to receive the data. The pointers to these buffers will be returned. If OCI_DYNAMIC_FETCH mode was selected, and the call to OCIDefineDynamic() is skipped, then the application can fetch data piecewise using OCI calls. For more information about OCI_DYNAMIC_FETCH mode, see the section "Runtime Data Allocation and Piecewise Operations" on page 5-16.

This descriptor is bound to a bind variable of data type SQLT_RSET (result set). The descriptor has to be converted into a statement handle using a function - OCIResultSetToStmt() - which can then be passed to OCIDefineByPos() and OCIStmtFetch() to retrieve the rows of the result set. OCI_DTYPE_ROWID - specifies generation of a ROWID descriptor of C type OCIRowid. OCI_DTYPE_COMPLEXOBJECTCOMP - specifies generation of a complex object retrieval descriptor of C type OCIComplexObjectComp. xtramemsz (IN) - specifies an amount of user memory to be allocated for use by the application. usrmempp (OUT) - returns a pointer to the user memory of size xtramemsz allocated by the call for the user. Related Functions OCIDescFree() OCIDescFree() Name OCI Free DESCriptor Purpose Deallocates a previously allocated descriptor. Syntax sword OCIDescFree ( void *descp, ub4 type); Comments This call frees up storage associated with the descriptor, corresponding to the type specified in type. Returns OCI_SUCCESS or OCI_INVALID_HANDLE. All descriptors must be explicitly deallocated. OCI will not deallocate a descriptor if the environment handle is deallocated. Parameters descp (IN) - an allocated descriptor. type (IN) - specifies the type of storage to be freed. The specific types are: OCI_DTYPE_SNAP - snapshot descriptor OCI_DTYPE_LOB - a LOB data type descriptor OCI_DTYPE_RSET - a descriptor that references a result set (a number of rows as a result of a query). OCI_DTYPE_ROWID - a ROWID descriptor OCI_DTYPE_COMPLEXOBJECTCOMP - a complex object retrieval descriptor Related Functions OCIDescAlloc() OCIDescribeAny() Name OCI DeSCribe Any Purpose Describes existing schema objects. Syntax sword OCIDescribeAny ( OCISvcCtx *svchp, OCIError *errhp, void *objptr, ub4 objnm_len, ub1 objptr_typ, ub1 info_level, ub1 objtype, OCIDesc *dschp ); Comments This is a generic describe call that describes existing schema objects: tables, views, synonyms, procedures, functions, packages, sequences, and types. As a result of this call, the describe handle is populated with the object-specific attributes which can be obtained through an OCIAttrGet() call. An OCIParamGet() on the describe handle returns a parameter descriptor for a specified position. Parameter positions begin with 1. Calling OCIAttrGet() on the parameter descriptor returns the specific attributes of a stored procedure or function parameter or a table column descriptor as the case may be. These subsequent calls do not need an extra round trip to the server because the entire schema object description cached on the client side by OCIDescribeAny(). Calling OCIAttrGet() on the describe handle can also return the total number of positions. See the section "Describing" on page 2-33 for more information about describe operations. Parameters TO BE UPDATED svchp (IN/OUT) - a service context handle. errhp (IN/OUT) - an error handle which can be passed to OCIErrorGet() for diagnostic information in the event of an error. objptr (IN) - the name of the object (a null-terminated string) to be described. Only procedure or function names are valid when connected to an Oracle7 Server. objptr_len (IN) - the length of the string. Must be non-zero. objptr_typ (IN) - Must be OCI_OTYPE_NAME, OCI_OTYPE_REF, or OCI_OTYPE_PTR. info_level (IN) - reserved for future extensions. Pass OCI_DEFAULT. objtype (IN/OUT) - object type. dschp (IN/OUT) - a describe handle that is populated with describe information about the object after the call. Related Functions OCIAttrGet() OCIEnvCreate() Name OCI ENVironment CREATE Purpose This function creates and initializes an environment for the rest of the OCI functions to work under. This call is a replacement for both the OCIInitialize and OCIEnvInit calls. Syntax sword OCIEnvCreate ( OCIEnv **envhpp, ub4 mode, const void *ctxp, const void *(*malocfp) (void *ctxp, size_t size), const void *(*ralocfp) (void *ctxp, void *memptr, size_t newsize), const void (*mfreefp) ( void *ctxp, void *memptr)) size_t xtramemsz, void **usrmempp ); Comments This call creates an environment for all the OCI calls using the modes specified by the user. This call can be used instead of the two calls OCIInitialize and OCIEnvInit. This function returns an environment handle which is then used by the remaining OCI functions. There can be multiple environments in OCI each with its own environment modes. This function also performs any process level initialization if required by any mode. For example if the user wants to initialize an environment as OCI_THREADED, then all libraries that are used by OCI are also initialized in the threaded mode. This call should be invoked before anny other OCI call and should be used instead of the OCIInitialize and OCIEnvInit calls. This is the recommended call, although OCIInitialize and OCIEnvInit calls will still be supported for backward compatibility. envpp (OUT) - a pointer to a handle to the environment. mode (IN) - specifies initialization of the mode. The valid modes are: OCI_DEFAULT - default mode. OCI_THREADED - threaded environment. In this mode, internal data structures are protected from concurrent accesses by multiple threads. OCI_OBJECT - will use navigational object interface. ctxp (IN) - user defined context for the memory call back routines. malocfp (IN) - user-defined memory allocation function. If mode is OCI_THREADED, this memory allocation routine must be thread safe. ctxp - context pointer for the user-defined memory allocation function. size - size of memory to be allocated by the user-defined memory allocation function ralocfp (IN) - user-defined memory re-allocation function. If mode is OCI_THREADED, this memory allocation routine must be thread safe. ctxp - context pointer for the user-defined memory reallocation function. memp - pointer to memory block newsize - new size of memory to be allocated mfreefp (IN) - user-defined memory free function. If mode is OCI_THREADED, this memory free routine must be thread safe. ctxp - context pointer for the user-defined memory free function. memptr - pointer to memory to be freed xtramemsz (IN) - specifies the amount of user memory to be allocated. usrmempp (OUT) - returns a pointer to the user memory of size xtramemsz allocated by the call for the user. Example Related Functions OCIInitialize, OCIEnvInit OCIEnvNlsCreate() Name OCI ENVironment CREATE with NLS info Purpose This function does almost everything OCIEnvCreate does, plus enabling setting of charset and ncharset programmatically, except OCI_UTF16 mode.

The parameters have the same meaning as the ones in OCIEnvCreate(). When charset or ncharset is non-zero, the corresponding character set will be used to replace the ones specified in NLS_LANG or NLS_NCHAR. Moreover, OCI_UTF16ID is allowed to be set as charset and ncharset. On the other hand, OCI_UTF16 mode is deprecated with this function. Applications can achieve the same effects by setting both charset and ncharset as OCI_UTF16ID. OCIEnvInit() Name OCI INITialize environment Purpose This call initializes the OCI environment handle. Syntax sword OCIEnvInit ( OCIEnv **envp, ub4 mode, size_t xtramemsz, void **usrmempp ); Comments Initializes the OCI environment handle. No changes are done on an initialized handle. If OCI_ERROR or OCI_SUCCESS_WITH_INFO is returned, the environment handle can be used to obtain ORACLE specific errors and diagnostics. This call is processed locally, without a server round-trip. Parameters envpp (OUT) - a pointer to a handle to the environment. mode (IN) - specifies initialization of an environment mode. The only valid mode is OCI_DEFAULT for default mode xtramemsz (IN) - specifies the amount of user memory to be allocated. usrmempp (OUT) - returns a pointer to the user memory of size xtramemsz allocated by the call for the user.

After the assignment, both locators refer to the same LOB data. For internal LOBs, the source locator's LOB data gets copied to the destination locator's LOB data only when the destination locator gets stored in the table. Therefore, issuing a flush of the object containing the destination locator will copy the LOB data. For FILEs only the locator that refers to the OS file is copied to the table. The OS file is not copied. Note: The only difference between this and OCILobLocatorAssign is that this takes an environment handle whereas OCILobLocatorAssign takes an OCI service handle Parameters envhp (IN/OUT) - OCI environment handle initialized in object mode. errhp (IN/OUT) - The OCI error handle. If there is an error, it is recorded in errhp and this function returns OCI_ERROR. Diagnostic information can be obtained by calling OCIErrorGet(). src_locp (IN) - LOB locator to copy from. dst_locpp (IN/OUT) - LOB locator to copy to.

Parameters envhp (IN/OUT) - OCI environment handle initialized in object mode. errhp (IN/OUT) - error handle. The OCI error handle. If there is an error, it is recorded in err and this function returns OCI_ERROR. Diagnostic information can be obtained by calling OCIErrorGet(). locp (IN) - LOB locator for which to get the character set form. csfrm(OUT) - character set form of the input LOB locator. If the input locator is for a BLOB or a BFILE, csfrm is set to 0 since there is no concept of a character set for binary LOBs/FILEs. The caller must allocate space for the csfrm (ub1) and not write into the space. See also OCIErrorGet(), OCILobCharSetId(), OCILobLocatorIsInit OCILobCharSetId() Name OCI Lob get Character Set IDentifier Purpose Gets the LOB locator's character set ID, if any. Syntax sword OCILobCharSetId ( OCIEnv *envhp, OCIError *errhp, const OCILobLocator *locp, ub2 *csid ); Comments Returns the character set ID of the input LOB locator in the cid output parameter. Parameters envhp (IN/OUT) - OCI environment handle initialized in object mode. errhp (IN/OUT) - error handle. The OCI error handle.

Syntax sword OCILobCopy ( OCISvcCtx *svchp, OCIError *errhp, OCILobLocator *dst_locp, OCILobLocator *src_locp, ub4 amount, ub4 dst_offset, ub4 src_offset ); Comments Copies a portion of a LOB value into another LOB as specified. The data is copied from the source to the destination. The source (src_locp) and the destination (dlopb) LOBs must already exist. If the data already exists at the destination's start position, it is overwritten with the source data. If the destination's start position is beyond the end of the current data, a hole is created from the end of the data to the beginning of the newly written data from the source. The destination LOB is extended to accommodate the newly written data if it extends beyond the current length of the destination LOB. It is an error to extend the destination LOB beyond the maximum length allowed or to try to copy from a NULL LOB. Parameters svchp (IN) - the service context handle. errhp (IN/OUT) - an error handle which can be passed to OCIErrorGet() for diagnostic information in the event of an error. dst_locp (IN/OUT) - a locator uniquely referencing the destination LOB. src_locp (IN/OUT) - a locator uniquely referencing the source LOB. amount (IN) - the number of character or bytes, as appropriate, to be copied. dst_offset (IN) - this is the absolute offset for the destination LOB. For character LOBs it is the number of characters from the beginning of the LOB at which to begin writing. For binary LOBs it is the number of bytes from the beginning of the lob from which to begin reading. The offset starts at 1. src_offset (IN) - this is the absolute offset for the source LOB. For character LOBs it is the number of characters from the beginning of the LOB, for binary LOBs it is the number of bytes. Starts at 1.

Syntax sword OCILobLoadFromFile ( OCISvcCtx *svchp, OCIError *errhp, OCILobLocator *dst_locp, OCILobLocator *src_filep, ub4 amount, ub4 dst_offset, ub4 src_offset ); Comments Loads/copies a portion or all of a file value into an internal LOB as specified. The data is copied from the source file to the destination internal LOB (BLOB/CLOB). No character set conversions are performed when copying the bfile data to a clob/nclob. The bfile data must already be in the same character set as the clob/nclob in the database. No error checking is performed to verify this. The source (src_filep) and the destination (dst_locp) LOBs must already exist. If the data already exists at the destination's start position, it is overwritten with the source data. If the destination's start position is beyond the end of the current data, a hole is created from the end of the data to the beginning of the newly written data from the source. The destination LOB is extended to accommodate the newly written data if it extends beyond the current length of the destination LOB. It is an error to extend the destination LOB beyond the maximum length allowed or to try to copy from a NULL LOB. Parameters svchp (IN) - the service context handle. errhp (IN/OUT) - an error handle which can be passed to OCIErrorGet() for diagnostic information in the event of an error. dst_locp (IN/OUT) - a locator uniquely referencing the destination internal LOB which may be of type blob, clob, or nclob. src_filep (IN/OUT) - a locator uniquely referencing the source BFILE. amount (IN) - the number of bytes to be copied. dst_offset (IN) - this is the absolute offset for the destination LOB. For character LOBs it is the number of characters from the beginning of the LOB at which to begin writing. For binary LOBs it is the number of bytes from the beginning of the lob from which to begin reading. The offset starts at 1. src_offset (IN) - this is the absolute offset for the source BFILE. It is the number of bytes from the beginning of the LOB. The offset starts at 1.

Syntax sword OCILobLocatorAssign ( OCISvcCtx *svchp, OCIError *errhp, const OCILobLocator *src_locp, OCILobLocator **dst_locpp ); Comments Assign source locator to destination locator. After the assignment, both locators refer to the same LOB data. For internal LOBs, the source locator's LOB data gets copied to the destination locator's LOB data only when the destination locator gets stored in the table. Therefore, issuing a flush of the object containing the destination locator will copy the LOB data. For FILEs only the locator that refers to the OS file is copied to the table. The OS file is not copied. Note : the only difference between this and OCILobAssign is that this takes a OCI service handle pointer instead of a OCI environment handle pointer Parameters svchp (IN/OUT) - OCI service handle initialized in object mode. errhp (IN/OUT) - The OCI error handle. If there is an error, it is recorded in errhp and this function returns OCI_ERROR. Diagnostic information can be obtained by calling OCIErrorGet(). src_locp (IN) - LOB locator to copy from. dst_locpp (IN/OUT) - LOB locator to copy to.

Starts from 1. amtp (IN/OUT) - On input, the number of character or bytes to be read. On output, the actual number of bytes or characters read. If the amount of bytes to be read is larger than the buffer length it is assumed that the LOB is being read in a streamed mode. On input if this value is 0, then the data shall be read in streamed mode from the LOB until the end of LOB. If the data is read in pieces, *amtp always contains the length of the last piece read. If a callback function is defined, then this callback function will be invoked each time bufl bytes are read off the pipe. Each piece will be written into bufp. If the callback function is not defined, then OCI_NEED_DATA error code will be returned. The application must invoke the LOB read over and over again to read more pieces of the LOB until the OCI_NEED_DATA error code is not returned. The buffer pointer and the length can be different in each call if the pieces are being read into different sizes and location. bufp (IN) - the pointer to a buffer into which the piece will be read.

If LOB data already exists it is overwritten with the data stored in the buffer. The buffer can be written to the LOB in a single piece with this call, or it can be provided piecewise using callbacks or a standard polling method. If this value of the piece parameter is OCI_FIRST_PIECE, data must be provided through callbacks or polling. If a callback function is defined in the cbfp parameter, then this callback function will be invoked to get the next piece after a piece is written to the pipe. Each piece will be written from bufp. If no callback function is defined, then OCILobWrite() returns the OCI_NEED_DATA error code. The application must all OCILobWrite() again to write more pieces of the LOB. In this mode, the buffer pointer and the length can be different in each call if the pieces are of different sizes and from different locations. A piece value of OCI_LAST_PIECE terminates the piecewise write. Parameters svchp (IN/OUT) - the service context handle. errhp (IN/OUT) - an error handle which can be passed to OCIErrorGet() for diagnostic information in the event of an error. locp (IN/OUT) - a LOB locator that uniquely references a LOB. offset (IN) - On input, it is the absolute offset, for character LOBs in the number of characters from the beginning of the LOB, for binary LOBs it is the number of bytes.

Even if the data is being written in pieces, bufp must contain the first piece of the LOB when this call is invoked. bufl (IN) - the length of the buffer in bytes. Note: This parameter assumes an 8-bit byte. If your platform uses a longer byte, the value of bufl must be adjusted accordingly. piece (IN) - which piece of the buffer is being written. The default value for this parameter is OCI_ONE_PIECE, indicating the buffer will be written in a single piece. The following other values are also possible for piecewise or callback mode: OCI_FIRST_PIECE, OCI_NEXT_PIECE and OCI_LAST_PIECE. amtp (IN/OUT) - On input, takes the number of character or bytes to be written. On output, returns the actual number of bytes or characters written.

If the data is written in pieces, *amtp will contain the total length of the pieces written at the end of the call (last piece written) and is undefined in between. (Note it is different from the piecewise read case) ctxp (IN) - the context for the call back function. Can be NULL. cbfp (IN) - a callback that may be registered to be called for each piece in a piecewise write. If this is NULL, the standard polling method will be used. The callback function must return OCI_CONTINUE for the write to continue. If any other error code is returned, the LOB write is aborted. The callback takes the following parameters: ctxp (IN) - the context for the call back function. Can be NULL. bufp (IN/OUT) - a buffer pointer for the piece. lenp (IN/OUT) - the length of the buffer (in octets) and the length of current piece in bufp (out octets). piecep (OUT) - which piece - OCI_NEXT_PIECE or OCI_LAST_PIECE. csid - the character set ID of the buffer data csfrm - the character set form of the buffer data Related Functions OCILobGetStorageLimit() Name OCI Lob Get Storage Limit Purpose To get the maximum Length of a LOB in bytes that can be stored in the database.

This call is similar to OCISessionBegin() with the following differences: If the user authentication is already established, it authenticates the account using the old password and then changes the password to the new password If the user authentication is not established, it establishes a user authentication and authenticates the account using the old password, then changes the password to the new password. This call is useful when the password of an account is expired and OCISessionBegin() returns an error or warning which indicates that the password has expired. Parameters svchp (IN/OUT) - a handle to a service context. The service context handle must be initialized and have a server context handle associated with it. errhp (IN) - an error handle which can be passed to OCIErrorGet() for diagnostic information in the event of an error. user_name (IN) - specifies the user name. It points to a character string, whose length is specified in usernm_len. This parameter must be NULL if the service context has been initialized with an authentication handle. usernm_len (IN) - the length of the user name string specified in user_name.

Must be called if a OCIBreak call had been issued while a non-blocking operation was in progress. Syntax sword OCIReset ( void *hndlp, OCIError *errhp); Comments This call is called in non-blocking mode ONLY. Resets the interrupted asynchronous operation and protocol. Must be called if a OCIBreak call had been issued while a non-blocking operation was in progress.

Related Functions OCIDescAlloc() OCIServerAttach() Name OCI ATtaCH to server Purpose Creates an access path to a data source for OCI operations. Syntax sword OCIServerAttach ( OCIServer *srvhp, OCIError *errhp, const OraText *dblink, sb4 dblink_len, ub4 mode); Comments This call is used to create an association between an OCI application and a particular server. This call initializes a server context handle, which must have been previously allocated with a call to OCIHandleAlloc(). The server context handle initialized by this call can be associated with a service context through a call to OCIAttrSet(). Once that association has been made, OCI operations can be performed against the server. If an application is operating against multiple servers, multiple server context handles can be maintained. OCI operations are performed against whichever server context is currently associated with the service context. Parameters srvhp (IN/OUT) - an uninitialized server context handle, which gets initialized by this call. Passing in an initialized server handle causes an error. errhp (IN/OUT) - an error handle which can be passed to OCIErrorGet() for diagnostic information in the event of an error. dblink (IN) - specifies the database (server) to use. This parameter points to a character string which specifies a connect string or a service point. If the connect string is NULL, then this call attaches to the default host. The length of connstr is specified in connstr_len. The connstr pointer may be freed by the caller on return. dblink_len (IN) - the length of the string pointed to by connstr. For a valid connect string name or alias, connstr_len must be non-zero. mode (IN) - specifies the various modes of operation. For release 8.0, pass as OCI_DEFAULT - in this mode, calls made to the server on this server context are made in blocking mode.

Syntax sword OCIServerVersion ( void *hndlp, OCIError *errhp, OraText *bufp, ub4 bufsz ub1 hndltype ); Comments This call returns the version string of the Oracle server. For example, the following might be returned as the version string if your application is running against a 7.3.2 server: Oracle7 Server Release 7.3.2.0.0 - Production Release PL/SQL Release 2.3.2.0.0 - Production CORE Version 3.5.2.0.0 - Production TNS for SEQUENT DYNIX/ptx: Version 2.3.2.0.0 - Production NLSRTL Version 3.2.2.0.0 - Production Parameters hndlp (IN) - the service context handle or the server context handle. errhp (IN) - an error handle which can be passed to OCIErrorGet() for diagnostic information in the event of an error. bufp (IN) - the buffer in which the version information is returned. bufsz (IN) - the length of the buffer. hndltype (IN) - the type of handle passed to the function. Related Functions OCISessionBegin() Name OCI Session Begin and authenticate user Purpose Creates a user authentication and begins a user session for a given server. Syntax sword OCISessionBegin ( OCISvcCtx *svchp, OCIError *errhp, OCISession *usrhp, ub4 credt, ub4 mode); Comments For Oracle8, OCISessionBegin() must be called for any given server handle before requests can be made against it. Also, OCISessionBegin() only supports authenticating the user for access to the Oracle server specified by the server handle in the service context. In other words, after OCIServerAttach() is called to initialize a server handle, OCISessionBegin() must be called to authenticate the user for that given server. When OCISessionBegin() is called for the first time for the given server handle, the initialized authentication handle is called a primary authentication context. A primary authentication context may not be created with the OCI_MIGRATE mode. Also, only one primary authentication context can be created for a given server handle and the primary authentication context c an only ever be used with that server handle. If the primary authentication context is set in a service handle with a different server handle, then an error will result. After OCISessionBegin() has been called for the server handle, and the primary authentication context is set in the service handle, OCISessionBegin() may be called again to initialize another authentication handle with different (or the same) credentials. When OCISessionBegin() is called with a service handle set with a primary authentication context, the returned authentication context in authp is called a user authentication context. As many user authentication contexts may be initialized as desired. User authentication contexts may be created with the OCI_MIGRATE mode. If the OCI_MIGRATE mode is not specified, then the user authentication context can only ever be used with the same server handle set in svchp. If OCI_MIGRATE mode is specified, then the user authentication may be set with different server handles. However, the user authentication context is restricted to use with only server handles which resolve to the same database instance and that have equivalent primary authentication contexts. Equivalent authentication contexts are those which were authenticated as the same database user. OCI_SYSDBA, OCI_SYSOPER, OCI_SYSASM, and OCI_PRELIM_AUTH may only be used with a primary authentication context. To provide credentials for a call to OCISessionBegin(), one of two methods are supported. The first is to provide a valid username and password pair for database authentication in the user authentication handle passed to OCISessionBegin(). This involves using OCIAttrSet() to set the OCI_ATTR_USERNAME and OCI_ATTR_PASSWORD attributes on the authentication handle. Then OCISessionBegin() is called with OCI_CRED_RDBMS. Note: When the authentication handle is terminated using OCISessionEnd(), the username and password attributes remain unchanged and thus can be re-used in a future call to OCISessionBegin(). Otherwise, they must be reset to new values before the next OCISessionBegin() call. The second type of credentials supported are external credentials. No attributes need to be set on the authentication handle before calling OCISessionBegin(). The credential type is OCI_CRED_EXT. This is equivalent to the Oracle7 `connect /' syntax. If values have been set for OCI_ATTR_USERNAME and OCI_ATTR_PASSWORD, then these are ignored if OCI_CRED_EXT is used. Parameters svchp (IN) - a handle to a service context. There must be a valid server handle set in svchp. errhp (IN) - an error handle to the retrieve diagnostic information. usrhp (IN/OUT) - a handle to an authentication context, which is initialized by this call. credt (IN) - specifies the type of credentials to use for authentication. Valid values for credt are: OCI_CRED_RDBMS - authenticate using a database username and password pair as credentials. The attributes OCI_ATTR_USERNAME and OCI_ATTR_PASSWORD should be set on the authentication context before this call. OCI_CRED_EXT - authenticate using external credentials. No username or password is provided. mode (IN) - specifies the various modes of operation. Valid modes are: OCI_DEFAULT - in this mode, the authentication context returned may only ever be set with the same server context specified in svchp. This establishes the primary authentication context. OCI_MIGRATE - in this mode, the new authentication context may be set in a service handle with a different server handle. This mode establishes the user authentication context. OCI_SYSDBA - in this mode, the user is authenticated for SYSDBA access. OCI_SYSOPER - in this mode, the user is authenticated for SYSOPER access. OCI_SYSASM - in this mode, the user is authenticated for SYSASM access. Note that only an ASM instance can grant SYSASM access. OCI_PRELIM_AUTH - this mode may only be used with OCI_SYSDBA, OCI_SYSASM, or OCI_SYSOPER to authenticate for certain administration tasks. Related Functions OCISessionEnd() OCISessionEnd() Name OCI Terminate user Authentication Context Purpose Terminates a user authentication context created by OCISessionBegin() Syntax sword OCISessionEnd ( OCISvcCtx *svchp, OCIError *errhp, OCISession *usrhp, ub4 mode); Comments The user security context associated with the service context is invalidated by this call. Storage for the authentication context is not freed. The transaction specified by the service context is implicitly committed. The transaction handle, if explicitly allocated, may be freed if not being used. Resources allocated on the server for this user are freed. The authentication handle may be reused in a new call to OCISessionBegin(). Parameters svchp (IN/OUT) - the service context handle. There must be a valid server handle and user authentication handle associated with svchp. errhp (IN/OUT) - an error handle which can be passed to OCIErrorGet() for diagnostic information in the event of an error. usrhp (IN) - de-authenticate this user. If this parameter is passed as NULL, the user in the service context handle is de-authenticated. mode (IN) - the only valid mode is OCI_DEFAULT. Example In this example, an authentication context is destroyed. Related Functions OCISessionBegin() OCIStmtExecute() Name OCI EXECute Purpose This call associates an application request with a server. Syntax sword OCIStmtExecute ( OCISvcCtx *svchp, OCIStmt *stmtp, OCIError *errhp, ub4 iters, ub4 rowoff, const OCISnapshot *snap_in, OCISnapshot *snap_out, ub4 mode ); Comments This function is used to execute a prepared SQL statement. Using an execute call, the application associates a request with a server. On success, OCI_SUCCESS is returned. If a SELECT statement is executed, the description of the select list follows implicitly as a response. This description is buffered on the client side for describes, fetches and define type conversions. Hence it is optimal to describe a select list only after an execute. Also for SELECT statements, some results are available implicitly. Rows will be received and buffered at the end of the execute. For queries with small row count, a prefetch causes memory to be released in the server if the end of fetch is reached, an optimization that may result in memory usage reduction. Set attribute call has been defined to set the number of rows to be prefetched per result set. For SELECT statements, at the end of the execute, the statement handle implicitly maintains a reference to the service context on which it is executed. It is the user's responsibility to maintain the integrity of the service context. If the attributes of a service context is changed for executing some operations on this service context, the service context must be restored to have the same attributes, that a statement was executed with, prior to a fetch on the statement handle. The implicit reference is maintained until the statement handle is freed or the fetch is cancelled or an end of fetch condition is reached. Note: If output variables are defined for a SELECT statement before a call to OCIStmtExecute(), the number of rows specified by iters will be fetched directly into the defined output buffers and additional rows equivalent to the prefetch count will be prefetched. If there are no additional rows, then the fetch is complete without calling OCIStmtFetch(). The execute call will return errors if the statement has bind data types that are not supported in an Oracle7 server. Parameters svchp (IN/OUT) - service context handle. stmtp (IN/OUT) - an statement handle - defines the statement and the associated data to be executed at the server. It is invalid to pass in a statement handle that has bind of data types only supported in release 8.0 when srvchp points to an Oracle7 server. errhp (IN/OUT) - an error handle which can be passed to OCIErrorGet() for diagnostic information in the event of an error. If the statement is being batched and it is successful, then this handle will contain this particular statement execution specific errors returned from the server when the batch is flushed. iters (IN) - the number of times this statement is executed for non-Select statements. For Select statements, if iters is non-zero, then defines must have been done for the statement handle. The execution fetches iters rows into these predefined buffers and prefetches more rows depending upon the prefetch row count. This function returns an error if iters=0 for non-SELECT statements. rowoff (IN) - the index from which the data in an array bind is relevant for this multiple row execution. snap_in (IN) - this parameter is optional. if supplied, must point to a snapshot descriptor of type OCI_DTYPE_SNAP. The contents of this descriptor must be obtained from the snap_out parameter of a previous call. The descriptor is ignored if the SQL is not a SELECT. This facility allows multiple service contexts to ORACLE to see the same consistent snapshot of the database's committed data. However, uncommitted data in one context is not visible to another context even using the same snapshot. snap_out (OUT) - this parameter optional. if supplied, must point to a descriptor of type OCI_DTYPE_SNAP. This descriptor is filled in with an opaque representation which is the current ORACLE "system change number" suitable as a snap_in input to a subsequent call to OCIStmtExecute(). This descriptor should not be used any longer than necessary in order to avoid "snapshot too old" errors. mode (IN) - The modes are: If OCI_DEFAULT_MODE, the default mode, is selected, the request is immediately executed. Error handle contains diagnostics on error if any. OCI_EXACT_FETCH - if the statement is a SQL SELECT, this mode is only valid if the application has set the prefetch row count prior to this call. In this mode, the OCI library will get up to the number of rows specified (i.e., prefetch row count plus iters). If the number of rows returned by the query is greater than this value, OCI_ERROR will be returned with ORA-01422 as the implementation specific error in a diagnostic record. If the number of rows returned by the query is smaller than the prefetch row count, OCI_SUCCESS_WITH_INFO will be returned with ORA-01403 as the implementation specific error. The prefetch buffer size is ignored and the OCI library tries to allocate all the space required to contain the prefetched rows. The exact fetch semantics apply to only the top level rows. No more rows can be fetched for this query at the end of the call. OCI_KEEP_FETCH_STATE - the result set rows (not yet fetched) of this statement executed in this transaction will be maintained when the transaction is detached for migration. By default, a query is cancelled when a transaction is detached for migration. This mode is the default mode when connected to a V7 server. Related Functions OCIStmtPrepare() OCIStmtFetch() Name OCI FetCH Purpose Fetches rows from a query. Syntax sword OCIStmtFetch ( OCIStmt *stmtp, OCIError *errhp, ub4 nrows, ub2 orientation, ub4 mode); Comments The fetch call is a local call, if prefetched rows suffice. However, this is transparent to the application. If LOB columns are being read, LOB locators are fetched for subsequent LOB operations to be performed on these locators. Prefetching is turned off if LONG columns are involved. A fetch with nrows set to 0 rows effectively cancels the fetch for this statement. Parameters stmtp (IN) - a statement (application request) handle. errhp (IN) - an error handle which can be passed to OCIErrorGet() for diagnostic information in the event of an error. nrows (IN) - number of rows to be fetched from the current position. orientation (IN) - for release 8.0, the only acceptable value is OCI_FETCH_NEXT, which is also the default value. mode (IN) - for release 8.0, beta-1, the following mode is defined. OCI_DEFAULT - default mode OCI_EOF_FETCH - indicates that it is the last fetch from the result set. If nrows is non-zero, setting this mode effectively cancels fetching after retrieving nrows, otherwise it cancels fetching immediately. Related Functions OCIAttrGet() OCIStmtFetch2() Name OCI FetCH2 Purpose Fetches rows from a query. Syntax sword OCIStmtFetch2 ( OCIStmt *stmtp, OCIError *errhp, ub4 nrows, ub2 orientation, ub4 scrollOffset, ub4 mode); Comments The fetch call works similar to the OCIStmtFetch call with the addition of the fetchOffset parameter. It can be used on any statement handle, whether it is scrollable or not. For a non-scrollable statement handle, the only acceptable value will be OCI_FETCH_NEXT, and the fetchOffset parameter will be ignored. Applications are encouraged to use this new call. A fetchOffset with OCI_FETCH_RELATIVE is equivalent to OCI_FETCH_CURRENT with a value of 0, is equivalent to OCI_FETCH_NEXT with a value of 1, and equivalent to OCI_FETCH_PRIOR with a value of -1. Note that the range of accessible rows is [1,OCI_ATTR_ROW_COUNT] beyond which an error could be raised if sufficient rows do not exist in The fetch call is a local call, if prefetched rows suffice. However, this is transparent to the application. If LOB columns are being read, LOB locators are fetched for subsequent LOB operations to be performed on these locators. Prefetching is turned off if LONG columns are involved. A fetch with nrows set to 0 rows effectively cancels the fetch for this statement. Parameters stmtp (IN) - a statement (application request) handle. errhp (IN) - an error handle which can be passed to OCIErrorGet() for diagnostic information in the event of an error. nrows (IN) - number of rows to be fetched from the current position. It defaults to 1 for orientation OCI_FETCH_LAST. orientation (IN) - The acceptable values are as follows, with OCI_FETCH_NEXT being the default value. OCI_FETCH_CURRENT gets the current row, OCI_FETCH_NEXT gets the next row from the current position, OCI_FETCH_FIRST gets the first row in the result set, OCI_FETCH_LAST gets the last row in the result set, OCI_FETCH_PRIOR gets the previous row from the current row in the result set, OCI_FETCH_ABSOLUTE will fetch the row number (specified by fetchOffset parameter) in the result set using absolute positioning, OCI_FETCH_RELATIVE will fetch the row number (specified by fetchOffset parameter) in the result set using relative positioning. scrollOffset(IN) - offset used with the OCI_FETCH_ABSOLUTE and OCI_FETCH_RELATIVE orientation parameters only. It specify the new current position for scrollable result set. It is ignored for non-scrollable result sets. mode (IN) - for release 8.0, beta-1, the following mode is defined. OCI_DEFAULT - default mode OCI_EOF_FETCH - indicates that it is the last fetch from the result set. If nrows is non-zero, setting this mode effectively cancels fetching after retrieving nrows, otherwise it cancels fetching immediately.

Syntax sword OCISvcCtxToLda ( OCISvcCtx *srvhp, OCIError *errhp, Lda_Def *ldap ); Comments Toggles between an Oracle8 service context handle and an Oracle7 Lda_Def. This function can only be called after a service context has been properly initialized. Once the service context has been translated to an Lda_Def, it can be used in release 7.x OCI calls (e.g., obindps(), ofen()). Note: If there are multiple service contexts which share the same server handle, only one can be in V7 mode at any time. The action of this call can be reversed by passing the resulting Lda_Def to the OCILdaToSvcCtx() function. Parameters svchp (IN/OUT) - the service context handle. errhp (IN/OUT) - an error handle which can be passed to OCIErrorGet() for diagnostic information in the event of an error. ldap (IN/OUT) - a Logon Data Area for V7-style OCI calls which is initialized by this call. Related Functions OCILdaToSvcCtx() OCITransCommit() Name OCI TX (transaction) CoMmit Purpose Commits the transaction associated with a specified service context. Syntax sword OCITransCommit ( OCISvcCtx *srvcp, OCIError *errhp, ub4 flags ); Comments The transaction currently associated with the service context is committed. If it is a distributed transaction that the server cannot commit, this call additionally retrieves the state of the transaction from the database to be returned to the user in the error handle. If the application has defined multiple transactions, this function operates on the transaction currently associated with the service context. If the application is working with only the implicit local transaction created when database changes are made, that implicit transaction is committed. If the application is running in the object mode, then the modified or updated objects in the object cache for this transaction are also committed. The flags parameter is used for one-phase commit optimization in distributed transactions. If the transaction is non-distributed, the flags parameter is ignored, and OCI_DEFAULT can be passed as its value. OCI applications managing global transactions should pass a value of OCI_TRANS_TWOPHASE to the flags parameter for a two-phase commit. The default is one-phase commit. Under normal circumstances, OCITransCommit() returns with a status indicating that the transaction has either been committed or rolled back. With distributed transactions, it is possible that the transaction is now in-doubt (i.e., neither committed nor aborted). In this case, OCITransCommit() attempts to retrieve the status of the transaction from the server. The status is returned. Parameters srvcp (IN) - the service context handle. errhp (IN) - an error handle which can be passed to OCIErrorGet() for diagnostic information in the event of an error. flags -see the "Comments" section above. Related Functions OCITransRollback() OCITransDetach() Name OCI TX (transaction) DeTach Purpose Detaches a transaction. Syntax sword OCITransDetach ( OCISvcCtx *srvcp, OCIError *errhp, ub4 flags); Comments Detaches a global transaction from the service context handle. The transaction currently attached to the service context handle becomes inactive at the end of this call. The transaction may be resumed later by calling OCITransStart(), specifying a flags value of OCI_TRANS_RESUME. When a transaction is detached, the value which was specified in the timeout parameter of OCITransStart() when the transaction was started is used to determine the amount of time the branch can remain inactive before being deleted by the server's PMON process. Note: The transaction can be resumed by a different process than the one that detached it, provided that the transaction has the same authorization. Parameters srvcp (IN) - the service context handle. errhp (IN) - an error handle which can be passed to OCIErrorGet() for diagnostic information in the event of an error. flags (IN) - you must pass a value of OCI_DEFAULT for this parameter. Related Functions OCITransStart() OCITransForget() Name OCI TX (transaction) ForGeT Purpose Causes the server to forget a heuristically completed global transaction. Syntax sword OCITransForget ( OCISvcCtx *svchp, OCIError *errhp, ub4 flags); Comments Forgets a heuristically completed global transaction. The server deletes the status of the transaction from the system's pending transaction table. The XID of the transaction to be forgotten is set as an attribute of the transaction handle (OCI_ATTR_XID). Parameters srvcp (IN) - the service context handle - the transaction is rolled back. errhp (IN) - an error handle which can be passed to OCIErrorGet() for diagnostic information in the event of an error. flags (IN) - you must pass OCI_DEFAULT for this parameter. Related Functions OCITransCommit(), OCITransRollback() OCITransMultiPrepare() Name OCI Trans(action) Multi-Branch Prepare Purpose Prepares a transaction with multiple branches in a single call. Syntax sword OCITransMultiPrepare ( OCISvcCtx *svchp, ub4 numBranches, OCITrans **txns, OCIError **errhp); Comments Prepares the specified global transaction for commit. This call is valid only for distributed transactions. This call is an advanced performance feature intended for use only in situations where the caller is responsible for preparing all the branches in a transaction. Parameters srvcp (IN) - the service context handle. numBranches (IN) - This is the number of branches expected. It is also the array size for the next two parameters. txns (IN) - This is the array of transaction handles for the branches to prepare. They should all have the OCI_ATTR_XID set. The global transaction ID should be the same. errhp (IN) - This is the array of error handles. If OCI_SUCCESS is not returned, then these will indicate which branches received which errors. Related Functions OCITransPrepare() OCITransPrepare() Name OCI TX (transaction) PREpare Purpose Prepares a transaction for commit. Syntax sword OCITransPrepare ( OCISvcCtx *svchp, OCIError *errhp, ub4 flags); Comments Prepares the specified global transaction for commit. This call is valid only for distributed transactions. The call returns OCI_SUCCESS_WITH_INFO if the transaction has not made any changes. The error handle will indicate that the transaction is read-only. The flag parameter is not currently used. Parameters srvcp (IN) - the service context handle. errhp (IN) - an error handle which can be passed to OCIErrorGet() for diagnostic information in the event of an error. flags (IN) - you must pass OCI_DEFAULT for this parameter. Related Functions OCITransCommit(), OCITransForget() OCITransRollback() Name OCI TX (transaction) RoLlback Purpose Rolls back the current transaction. Syntax sword OCITransRollback ( void *svchp, OCIError *errhp, ub4 flags ); Comments The current transaction- defined as the set of statements executed since the last OCITransCommit() or since OCISessionBegin()-is rolled back. If the application is running under object mode then the modified or updated objects in the object cache for this transaction are also rolled back. An error is returned if an attempt is made to roll back a global transaction that is not currently active. Parameters svchp (IN) - a service context handle. The transaction currently set in the service context handle is rolled back. errhp -(IN) - an error handle which can be passed to OCIErrorGet() for diagnostic information in the event of an error. flags - you must pass a value of OCI_DEFAULT for this parameter. Related Functions OCITransCommit() OCITransStart() Name OCI TX (transaction) STart Purpose Sets the beginning of a transaction. Syntax sword OCITransStart ( OCISvcCtx *svchp, OCIError *errhp, uword timeout, ub4 flags); Comments This function sets the beginning of a global or serializable transaction. The transaction context currently associated with the service context handle is initialized at the end of the call if the flags parameter specifies that a new transaction should be started. The XID of the transaction is set as an attribute of the transaction handle (OCI_ATTR_XID) Parameters svchp (IN/OUT) - the service context handle. The transaction context in the service context handle is initialized at the end of the call if the flag specified a new transaction to be started. errhp (IN/OUT) - The OCI error handle. If there is an error, it is recorded in err and this function returns OCI_ERROR. Diagnostic information can be obtained by calling OCIErrorGet(). timeout (IN) - the time, in seconds, to wait for a transaction to become available for resumption when OCI_TRANS_RESUME is specified. When OCI_TRANS_NEW is specified, this value is stored and may be used later by OCITransDetach(). flags (IN) - specifies whether a new transaction is being started or an existing transaction is being resumed. Also specifies serializiability or read-only status. More than a single value can be specified. By default, a read/write transaction is started. The flag values are: OCI_TRANS_NEW - starts a new transaction branch. By default starts a tightly coupled and migratable branch. OCI_TRANS_TIGHT - explicitly specifies a tightly coupled branch OCI_TRANS_LOOSE - specifies a loosely coupled branch OCI_TRANS_RESUME - resumes an existing transaction branch. OCI_TRANS_READONLY - start a readonly transaction OCI_TRANS_SERIALIZABLE - start a serializable transaction Related Functions OCITransDetach() ******************************************************************************/ /*-----------------------Dynamic Callback Function Pointers------------------*/ typedef sb4 (*OCICallbackInBind)(void *ictxp, OCIBind *bindp, ub4 iter, ub4 index, void **bufpp, ub4 *alenp, ub1 *piecep, void **indp);

As a result, products that rely on all of OCIThread's functionality will not port to all platforms. Products that must port to all platforms must use only a subset of OCIThread's functionality. This issue is discussed further in later sections of this document. The OCIThread API is split into four main parts. Each part is described briefly here. The following subsections describe each in greater detail. 1. Initialization and Termination Calls These calls deal with the initialization and termination of OCIThread. Initialization of OCIThread initializes the OCIThread context which is a member of the OCI environment or session handle. This context is required for other OCIThread calls. 2. Passive Threading Primitives The passive threading primitives include primitives to manipulate mutual exclusion (mutex) locks, thread ID's, and thread-specific data keys. The reason that these primitives are described as 'passive' is that while their specifications allow for the existence of multiple threads, they do not require it. This means that it is possible for these primitives to be implemented according to specification in both single-threaded and multi-threaded environments. As a result, OCIThread clients that use only these primitives will not require the existence of multiple threads in order to work correctly, i.e., they will be able to work in single-threaded environments without branching code. 3. Active Threading Primitives Active threading primitives include primitives dealing with the creation, termination, and other manipulation of threads. The reason that these primitives are described as 'active' is that they can only be used in true multi-threaded environments. Their specifications explicitly require that it be possible to have multiple threads. If you need to determine at runtime whether or not you are in a multi-threaded environment, call OCIThreadIsMulti() before calling an OCIThread active primitive. 1.1 Initialization & Termination ================================== The types and functions described in this section are associated with the initialization and termination of the OCIThread package. OCIThread must be properly initialized before any of its functionality can be used. OCIThread's process initialization function, 'OCIThreadProcessInit()', must be called with care; see below. The observed behavior of the initialization and termination functions is the same regardless of whether OCIThread is in single-threaded or multi-threaded environment. It is OK to call the initialization functions from both generic and operating system specific (OSD) code. 1.1.1 Types OCIThreadContext - OCIThread Context ------------------------------------- Most calls to OCIThread functions take the OCI environment or session handle as a parameter. The OCIThread context is part of the OCI environment or session handle and it must be initialized by calling 'OCIThreadInit()'. Termination of the OCIThread context occurs by calling 'OCIThreadTerm()'. The OCIThread context is a private data structure. Clients must NEVER attempt to examine the contents of the context. 1.1.2 OCIThreadProcessInit OCIThreadProcessInit - OCIThread Process INITialization -------------------------------------------------------- Description This function should be called to perform OCIThread process initialization. Prototype void OCIThreadProcessInit(); Returns Nothing. Notes Whether or not this function needs to be called depends on how OCI Thread is going to be used. * In a single-threaded application, calling this function is optional. If it is called at all, the first call to it must occur before calls to any other OCIThread functions. Subsequent calls can be made without restriction; they will not have any effect. * In a multi-threaded application, this function MUST be called. The first call to it MUST occur 'strictly before' any other OCIThread calls; i.e., no other calls to OCIThread functions (including other calls to this one) can be concurrent with the first call. Subsequent calls to this function can be made without restriction; they will not have any effect. 1.1.3 OCIThreadInit OCIThreadInit - OCIThread INITialize ------------------------------------- Description This initializes OCIThread context. Prototype sword OCIThreadInit(void *hndl, OCIError *err); hndl(IN/OUT): The OCI environment or session handle. err(IN/OUT): The OCI error handle. If there is an error and OCI_ERROR is returned, the error is recorded in err and diagnostic information can be obtained by calling OCIErrorGet(). Returns OCI_SUCCESS, OCI_ERROR or OCI_INVALID_HANDLE. Notes It is illegal for OCIThread clients to try an examine the memory pointed to by the returned pointer. It is safe to make concurrent calls to 'OCIThreadInit()'. Unlike 'OCIThreadProcessInit()', there is no need to have a first call that occurs before all the others. The first time 'OCIThreadInit()' is called, it initilaizes the OCI Thread context. It also saves a pointer to the context in some system dependent manner. Subsequent calls to 'OCIThreadInit()' will return the same context. Each call to 'OCIThreadInit()' must eventually be matched by a call to 'OCIThreadTerm()'. OCIThreadTerm - OCIThread TERMinate ------------------------------------ Description This should be called to release the OCIThread context. It should be called exactly once for each call made to 'OCIThreadInit()'. Prototype sword OCIThreadTerm(void *hndl, OCIError *err); hndl(IN/OUT): The OCI environment or session handle. err(IN/OUT): The OCI error handle. If there is an error and OCI_ERROR is returned, the error is recorded in err and diagnostic information can be obtained by calling OCIErrorGet(). Returns OCI_SUCCESS, OCI_ERROR or OCI_INVALID_HANDLE. Notes It is safe to make concurrent calls to 'OCIThreadTerm()'. 'OCIThreadTerm()' will not do anything until it has been called as many times as 'OCIThreadInit()' has been called. When that happens, it terminates the OCIThread layer and frees the memory allocated for the context. Once this happens, the context should not be re-used. It will be necessary to obtain a new one by calling 'OCIThreadInit()'. OCIThreadIsMulti - OCIThread Is Multi-Threaded? ------------------------------------------------ Description This tells the caller whether the application is running in a multi-threaded environment or a single-threaded environment. Prototype boolean OCIThreadIsMulti(void); Returns TRUE if the environment is multi-threaded; FALSE if the environment is single-threaded. 1.2 Passive Threading Primitives ================================== 1.2.1 Types The passive threading primitives deal with the manipulation of mutex, thread ID's, and thread-specific data. Since the specifications of these primitives do not require the existence of multiple threads, they can be used both on multithreaded and single-threaded platforms. 1.2.1.1 OCIThreadMutex - OCIThread Mutual Exclusion Lock ----------------------------------------------------------- The type 'OCIThreadMutex' is used to represent a mutual exclusion lock (mutex). A mutex is typically used for one of two purposes: (i) to ensure that only one thread accesses a given set of data at a time, or (ii) to ensure that only one thread executes a given critical section of code at a time. Mutexes pointer can be declared as parts of client structures or as stand-alone variables. Before they can be used, they must be initialized using 'OCIThreadMutexInit()'. Once they are no longer needed, they must be destroyed using 'OCIThreadMutexDestroy()'. A mutex pointer must NOT be used after it is destroyed. A thread can acquire a mutex by using either 'OCIThreadMutexAcquire()' or 'OCIThreadMutexTry()'. They both ensure that only one thread at a time is allowed to hold a given mutex. A thread that holds a mutex can release it by calling 'OCIThreadMutexRelease()'. 1.2.1.2 OCIThreadKey - OCIThread Key for Thread-Specific Data ---------------------------------------------------------------- A key can be thought of as a process-wide variable that has a thread-specific value. What this means is that all the threads in a process can use any given key. However, each thread can examine or modify that key independently of the other threads. The value that a thread sees when it examines the key will always be the same as the value that it last set for the key. It will not see any values set for the key by the other threads. The type of the value held by a key is a 'void *' generic pointer. Keys can be created using 'OCIThreadKeyInit()'. When a key is created, its value is initialized to 'NULL' for all threads. A thread can set a key's value using 'OCIThreadKeySet()'. A thread can get a key's value using 'OCIThreadKeyGet()'. The OCIThread key functions will save and retrieve data SPECIFIC TO THE THREAD. When clients maintain a pool of threads and assign the threads to different tasks, it *may not* be appropriate for a task to use OCIThread key functions to save data associated with it. Here is a scenario of how things can fail: A thread is assigned to execute the initialization of a task. During the initialization, the task stored some data related to it in the thread using OCIThread key functions. After the initialization, the thread is returned back to the threads pool. Later, the threads pool manager assigned another thread to perform some operations on the task, and the task needs to retrieve those data it stored earlier in initialization. Since the task is running in another thread, it will not be able to retrieve the same data back! Applications that use thread pools should be aware of this and be cautious when using OCIThread key functions. 1.2.1.3 OCIThreadKeyDestFunc - OCIThread Key Destructor Function Type ------------------------------------------------------------------------ This is the type of a pointer to a key's destructor routine. Keys can be associated with a destructor routine when they are created (see 'OCIThreadKeyInit()'). A key's destructor routine will be called whenever a thread that has a non-NULL value for the key terminates. The destructor routine returns nothing and takes one parameter. The parameter will be the value that was set for key when the thread terminated. The destructor routine is guaranteed to be called on a thread's value in the key after the termination of the thread and before process termination. No more precise guarantee can be made about the timing of the destructor routine call; thus no code in the process may assume any post-condition of the destructor routine. In particular, the destructor is not guaranteed to execute before a join call on the terminated thread returns. 1.2.1.4 OCIThreadId - OCIThread Thread ID -------------------------------------------- Type 'OCIThreadId' is the type that will be used to identify a thread. At any given time, no two threads will ever have the same 'OCIThreadId'. However, 'OCIThreadId' values can be recycled; i.e., once a thread dies, a new thread may be created that has the same 'OCIThreadId' as the one that died. In particular, the thread ID must uniquely identify a thread T within a process, and it must be consistent and valid in all threads U of the process for which it can be guaranteed that T is running concurrently with U. The thread ID for a thread T must be retrievable within thread T. This will be done via OCIThreadIdGet(). The 'OCIThreadId' type supports the concept of a NULL thread ID: the NULL thread ID will never be the same as the ID of an actual thread. 1.2.2 Function prototypes for passive primitives -------------------------------------------------- 1.2.2.1 Mutex functions ------------------------- OCIThreadMutexInit - OCIThread MuteX Initialize ----------------------------------------------- Description This allocate and initializes a mutex. All mutexes must be initialized prior to use. Prototype sword OCIThreadMutexInit(void *hndl, OCIError *err, OCIThreadMutex **mutex); hndl(IN/OUT): The OCI environment or session handle. err(IN/OUT): The OCI error handle. If there is an error and OCI_ERROR is returned, the error is recorded in err and diagnostic information can be obtained by calling OCIErrorGet(). mutex(OUT): The mutex to initialize. Returns OCI_SUCCESS, OCI_ERROR or OCI_INVALID_HANDLE. Notes Multiple threads must not initialize the same mutex simultaneously. Also, a mutex must not be reinitialized until it has been destroyed (see 'OCIThreadMutexDestroy()'). OCIThreadMutexDestroy - OCIThread MuteX Destroy ----------------------------------------------- Description This destroys and deallocate a mutex. Each mutex must be destroyed once it is no longer needed. Prototype sword OCIThreadMutexDestroy(void *hndl, OCIError *err, OCIThreadMutex **mutex); hndl(IN/OUT): The OCI environment or session handle. err(IN/OUT): The OCI error handle. If there is an error and OCI_ERROR is returned, the error is recorded in err and diagnostic information can be obtained by calling OCIErrorGet(). mutex(IN/OUT): The mutex to destroy. Returns OCI_SUCCESS, OCI_ERROR or OCI_INVALID_HANDLE. Notes It is not legal to destroy a mutex that is uninitialized or is currently held by a thread. The destruction of a mutex must not occur concurrently with any other operations on the mutex. A mutex must not be used after it has been destroyed. OCIThreadMutexAcquire - OCIThread MuteX Acquire ----------------------------------------------- Description This acquires a mutex for the thread in which it is called. If the mutex is held by another thread, the calling thread is blocked until it can acquire the mutex. Prototype sword OCIThreadMutexAcquire(void *hndl, OCIError *err, OCIThreadMutex *mutex); hndl(IN/OUT): The OCI environment or session handle. err(IN/OUT): The OCI error handle. If there is an error, it is recorded in err and this function returns OCI_ERROR. Diagnostic information can be obtained by calling OCIErrorGet(). mutex(IN/OUT): The mutex to acquire. Returns OCI_SUCCESS, OCI_ERROR or OCI_INVALID_HANDLE. Notes It is illegal to attempt to acquire an uninitialized mutex. This function's behavior is undefined if it is used by a thread to acquire a mutex that is already held by that thread. OCIThreadMutexRelease - OCIThread MuteX Release ----------------------------------------------- Description This releases a mutex. If there are any threads blocked on the mutex, one of them will acquire it and become unblocked. Prototype sword OCIThreadMutexRelease(void *hndl, OCIError *err, OCIThreadMutex *mutex); hndl(IN/OUT): The OCI environment or session handle. err(IN/OUT): The OCI error handle. If there is an error and OCI_ERROR is returned, the error is recorded in err and diagnostic information can be obtained by calling OCIErrorGet(). mutex(IN/OUT): The mutex to release. Returns OCI_SUCCESS, OCI_ERROR or OCI_INVALID_HANDLE. Notes It is illegal to attempt to release an uninitialized mutex. It is also illegal for a thread to release a mutex that it does not hold. OCIThreadKeyInit - OCIThread KeY Initialize ------------------------------------------- Description This creates a key. Each call to this routine allocate and generates a new key that is distinct from all other keys. Prototype sword OCIThreadKeyInit(void *hndl, OCIError *err, OCIThreadKey **key, OCIThreadKeyDestFunc destFn); hndl(IN/OUT): The OCI environment or session handle. err(IN/OUT): The OCI error handle. If there is an error and OCI_ERROR is returned, the error is recorded in err and diagnostic information can be obtained by calling OCIErrorGet(). key(OUT): The 'OCIThreadKey' in which to create the new key. destFn(IN): The destructor for the key. NULL is permitted. Returns OCI_SUCCESS, OCI_ERROR or OCI_INVALID_HANDLE. Notes Once this function executes successfully, a pointer to an allocated and initialized key is return. That key can be used with 'OCIThreadKeyGet()' and 'OCIThreadKeySet()'. The initial value of the key will be 'NULL' for all threads. It is illegal for this function to be called more than once to create the same key (i.e., to be called more than once with the same value for the 'key' parameter). If the 'destFn' parameter is not NULL, the routine pointed to by 'destFn' will be called whenever a thread that has a non-NULL value for the key terminates. The routine will be called with one parameter. The parameter will be the key's value for the thread at the time at which the thread terminated. If the key does not need a destructor function, pass NULL for 'destFn'. OCIThreadKeyDestroy - OCIThread KeY DESTROY ------------------------------------------- Description Destroy and deallocate the key pointed to by 'key'. Prototype sword OCIThreadKeyDestroy(void *hndl, OCIError *err, OCIThreadKey **key); hndl(IN/OUT): The OCI environment or session handle. err(IN/OUT): The OCI error handle. If there is an error and OCI_ERROR is returned, the error is recorded in err and diagnostic information can be obtained by calling OCIErrorGet(). key(IN/OUT): The 'OCIThreadKey' in which to destroy the key. Returns OCI_SUCCESS, OCI_ERROR or OCI_INVALID_HANDLE. Notes This is different from the destructor function callback passed to the key create routine. This new destroy function 'OCIThreadKeyDestroy' is used to terminate any resources OCI THREAD acquired when it created 'key'. [The 'OCIThreadKeyDestFunc' callback type is a key VALUE destructor; it does in no way operate on the key itself.] This must be called once the user has finished using the key. Not calling the key destroy function may result in memory leaks. 1.2.2.2 Thread Key operations ------------------------------- OCIThreadKeyGet - OCIThread KeY Get value ----------------------------------------- Description This gets the calling thread's current value for a key. Prototype sword OCIThreadKeyGet(void *hndl, OCIError *err, OCIThreadKey *key, void **pValue); hndl(IN/OUT): The OCI environment or session handle. err(IN/OUT): The OCI error handle. If there is an error and OCI_ERROR is returned, the error is recorded in err and diagnostic information can be obtained by calling OCIErrorGet(). key(IN): The key. pValue(IN/OUT): The location in which to place the thread-specific key value. Returns OCI_SUCCESS, OCI_ERROR or OCI_INVALID_HANDLE. Notes It is illegal to use this function on a key that has not been created using 'OCIThreadKeyInit()'. If the calling thread has not yet assigned a value to the key, 'NULL' is placed in the location pointed to by 'pValue'. OCIThreadKeySet - OCIThread KeY Set value ----------------------------------------- Description This sets the calling thread's value for a key. Prototype sword OCIThreadKeySet(void *hndl, OCIError *err, OCIThreadKey *key, void *value); hndl(IN/OUT): The OCI environment or session handle. err(IN/OUT): The OCI error handle. If there is an error and OCI_ERROR is returned, the error is recorded in err and diagnostic information can be obtained by calling OCIErrorGet(). key(IN/OUT): The key. value(IN): The thread-specific value to set in the key. Returns OCI_SUCCESS, OCI_ERROR or OCI_INVALID_HANDLE. Notes It is illegal to use this function on a key that has not been created using 'OCIThreadKeyInit()'. 1.2.2.3 Thread Id -------------------- OCIThreadIdInit - OCIThread Thread Id INITialize -------------------------------------------------- Description Allocate and initialize the thread id 'tid'. Prototype sword OCIThreadIdInit(void *hndl, OCIError *err, OCIThreadId **tid); hndl(IN/OUT): The OCI environment or session handle. err(IN/OUT): The OCI error handle. If there is an error and OCI_ERROR is returned, the error is recorded in err and diagnostic information can be obtained by calling OCIErrorGet(). tid (OUT): Pointer to the thread ID to initialize. Returns OCI_SUCCESS, OCI_ERROR or OCI_INVALID_HANDLE. OCIThreadIdDestroy - OCIThread Thread Id DESTROY -------------------------------------------------- Description Destroy and deallocate the thread id 'tid'. Prototype sword OCIThreadIdDestroy(void *hndl, OCIError *err, OCIThreadId **tid); hndl(IN/OUT): The OCI environment or session handle. err(IN/OUT): The OCI error handle. If there is an error and OCI_ERROR is returned, the error is recorded in err and diagnostic information can be obtained by calling OCIErrorGet(). tid(IN/OUT): Pointer to the thread ID to destroy. Returns OCI_SUCCESS, OCI_ERROR or OCI_INVALID_HANDLE. Note 'tid' should be initialized by OCIThreadIdInit(). OCIThreadIdSet - OCIThread Thread Id Set ----------------------------------------- Description This sets one 'OCIThreadId' to another. Prototype sword OCIThreadIdSet(void *hndl, OCIError *err, OCIThreadId *tidDest, OCIThreadId *tidSrc); hndl(IN/OUT): The OCI environment or session handle. err(IN/OUT): The OCI error handle. If there is an error and OCI_ERROR is returned, the error is recorded in err and diagnostic information can be obtained by calling OCIErrorGet(). tidDest(OUT): This should point to the location of the 'OCIThreadId' to be set to. tidSrc(IN): This should point to the 'OCIThreadId' to set from. Returns OCI_SUCCESS, OCI_ERROR or OCI_INVALID_HANDLE. Notes 'tid' should be initialized by OCIThreadIdInit(). OCIThreadIdSetNull - OCIThread Thread Id Set Null --------------------------------------------------------- Description This sets the NULL thread ID to a given 'OCIThreadId'. Prototype sword OCIThreadIdSetNull(void *hndl, OCIError *err, OCIThreadId *tid); hndl(IN/OUT): The OCI environment or session handle. err(IN/OUT): The OCI error handle. If there is an error, it is recorded in err and this function returns OCI_ERROR. Diagnostic information can be obtained by calling OCIErrorGet(). tid(OUT): This should point to the 'OCIThreadId' in which to put the NULL thread ID. Returns OCI_SUCCESS, OCI_ERROR or OCI_INVALID_HANDLE. Notes 'tid' should be initialized by OCIThreadIdInit(). OCIThreadIdGet - OCIThread Thread Id Get ------------------------------------------ Description This retrieves the 'OCIThreadId' of the thread in which it is called. Prototype sword OCIThreadIdGet(void *hndl, OCIError *err, OCIThreadId *tid); hndl(IN/OUT): The OCI environment or session handle. err(IN/OUT): The OCI error handle. If there is an error and OCI_ERROR is returned, the error is recorded in err and diagnostic information can be obtained by calling OCIErrorGet(). tid(OUT): This should point to the location in which to place the ID of the calling thread. Returns OCI_SUCCESS, OCI_ERROR or OCI_INVALID_HANDLE. Notes 'tid' should be initialized by OCIThreadIdInit(). When OCIThread is used in a single-threaded environment, OCIThreadIdGet() will always place the same value in the location pointed to by 'tid'. The exact value itself is not important. The important thing is that it is not the same as the NULL thread ID and that it is always the same value. OCIThreadIdSame - OCIThread Thread Ids Same? ---------------------------------------------- Description This determines whether or not two 'OCIThreadId's represent the same thread. Prototype sword OCIThreadIdSame(void *hndl, OCIError *err, OCIThreadId *tid1, OCIThreadId *tid2, boolean *result); hndl(IN/OUT): The OCI environment or session handle. err(IN/OUT): The OCI error handle. If there is an error and OCI_ERROR is returned, the error is recorded in err and diagnostic information can be obtained by calling OCIErrorGet(). tid1(IN): Pointer to the first 'OCIThreadId'. tid2(IN): Pointer to the second 'OCIThreadId'. result(IN/OUT): Pointer to the result. Returns OCI_SUCCESS, OCI_ERROR or OCI_INVALID_HANDLE. Notes If 'tid1' and 'tid2' represent the same thread, 'result' is set to TRUE. Otherwise, 'result' is set to FALSE. 'result' is set to TRUE if both 'tid1' and 'tid2' are the NULL thread ID. 'ti1d' and 'tid2' should be initialized by OCIThreadIdInit(). OCIThreadIdNull - OCIThread Thread Id NULL? --------------------------------------------- Description This determines whether or not a given 'OCIThreadId' is the NULL thread ID. Prototype sword OCIThreadIdNull(void *hndl, OCIError *err, OCIThreadId *tid, boolean *result); hndl(IN/OUT): The OCI environment or session handle. err(IN/OUT): The OCI error handle. If there is an error and OCI_ERROR is returned, the error is recorded in err and diagnostic information can be obtained by calling OCIErrorGet(). tid(IN): Pointer to the 'OCIThreadId' to check. result(IN/OUT): Pointer to the result. Returns OCI_SUCCESS, OCI_ERROR or OCI_INVALID_HANDLE. Notes If 'tid' is the NULL thread ID, 'result' is set to TRUE. Otherwise, 'result' is set to FALSE. 'tid' should be initialized by OCIThreadIdInit(). 1.3 Active Threading Primitives ================================= The active threading primitives deal with the manipulation of actual threads. Because the specifications of most of these primitives require that it be possible to have multiple threads, they work correctly only in the enabled OCIThread; In the disabled OCIThread, they always return failure. The exception is OCIThreadHandleGet(); it may be called in a single-threaded environment, in which case it will have no effect. Active primitives should only be called by code running in a multi-threaded environment. You can call OCIThreadIsMulti() to determine whether the environment is multi-threaded or single-threaded. 1.3.1 Types -------------- 1.3.1.1 OCIThreadHandle - OCIThread Thread Handle ------------------------------------------------------ Type 'OCIThreadHandle' is used to manipulate a thread in the active primitives: OCIThreadJoin()and OCIThreadClose(). A thread handle opened by OCIThreadCreate() must be closed in a matching call to OCIThreadClose(). A thread handle is invalid after the call to OCIThreadClose(). The distinction between a thread ID and a thread handle in OCIThread usage follows the distinction between the thread ID and the thread handle on Windows NT. On many platforms, the underlying native types are the same. 1.3.2 Functions ------------------ OCIThreadHndInit - OCIThread HaNDle Initialize ---------------------------------------------- Description Allocate and initialize the thread handle. Prototype sword OCIThreadHndInit(void *hndl, OCIError *err, OCIThreadHandle **thnd); hndl(IN/OUT): The OCI environment or session handle. err(IN/OUT): The OCI error handle. If there is an error and OCI_ERROR is returned, the error is recorded in err and diagnostic information can be obtained by calling OCIErrorGet(). thnd(OUT): The address of pointer to the thread handle to initialize. Returns OCI_SUCCESS, OCI_ERROR or OCI_INVALID_HANDLE. OCIThreadHndDestroy - OCIThread HaNDle Destroy ---------------------------------------------- Description Destroy and deallocate the thread handle. Prototype sword OCIThreadHndDestroy(void *hndl, OCIError *err, OCIThreadHandle **thnd); hndl(IN/OUT): The OCI environment or session handle. err(IN/OUT): The OCI error handle. If there is an error and OCI_ERROR is returned, the error is recorded in err and diagnostic information can be obtained by calling OCIErrorGet(). thnd(IN/OUT): The address of pointer to the thread handle to destroy. Returns OCI_SUCCESS, OCI_ERROR or OCI_INVALID_HANDLE. Notes 'thnd' should be initialized by OCIThreadHndInit(). OCIThreadCreate - OCIThread Thread Create ----------------------------------------- Description This creates a new thread. Prototype sword OCIThreadCreate(void *hndl, OCIError *err, void (*start)(void *), void *arg, OCIThreadId *tid, OCIThreadHandle *tHnd); hndl(IN/OUT): The OCI environment or session handle. err(IN/OUT): The OCI error handle. If there is an error and OCI_ERROR is returned, the error is recorded in err and diagnostic information can be obtained by calling OCIErrorGet(). start(IN): The function in which the new thread should begin execution. arg(IN): The argument to give the function pointed to by 'start'. tid(IN/OUT): If not NULL, gets the ID for the new thread. tHnd(IN/OUT): If not NULL, gets the handle for the new thread. Returns OCI_SUCCESS, OCI_ERROR or OCI_INVALID_HANDLE. Notes The new thread will start by executing a call to the function pointed to by 'start' with the argument given by 'arg'. When that function returns, the new thread will terminate. The function should not return a value and should accept one parameter, a 'void *'. The call to OCIThreadCreate() must be matched by a call to OCIThreadClose() if and only if tHnd is non-NULL. If tHnd is NULL, a thread ID placed in *tid will not be valid in the calling thread because the timing of the spawned thread's termination is unknown. 'tid' should be initialized by OCIThreadIdInit(). 'thnd' should be initialized by OCIThreadHndInit(). OCIThreadJoin - OCIThread Thread Join ------------------------------------- Description This function allows the calling thread to 'join' with another thread. It blocks the caller until the specified thread terminates. Prototype sword OCIThreadJoin(void *hndl, OCIError *err, OCIThreadHandle *tHnd); hndl(IN/OUT): The OCI environment or session handle. err(IN/OUT): The OCI error handle. If there is an error and OCI_ERROR is returned, the error is recorded in err and diagnostic information can be obtained by calling OCIErrorGet(). tHnd(IN): The 'OCIThreadHandle' of the thread to join with. Returns OCI_SUCCESS, OCI_ERROR or OCI_INVALID_HANDLE. Notes 'thnd' should be initialized by OCIThreadHndInit(). The result of multiple threads all trying to join with the same thread is undefined. OCIThreadClose - OCIThread Thread Close --------------------------------------- Description This function should be called to close a thread handle. Prototype sword OCIThreadClose(void *hndl, OCIError *err, OCIThreadHandle *tHnd); hndl(IN/OUT): The OCI environment or session handle. err(IN/OUT): The OCI error handle. If there is an error and OCI_ERROR is returned, the error is recorded in err and diagnostic information can be obtained by calling OCIErrorGet(). tHnd(IN/OUT): The OCIThread thread handle to close. Returns OCI_SUCCESS, OCI_ERROR or OCI_INVALID_HANDLE. Notes 'thnd' should be initialized by OCIThreadHndInit(). Both thread handle and the thread ID that was returned by the same call to OCIThreadCreate() are invalid after the call to OCIThreadClose(). OCIThreadHandleGet - OCIThread Thread Get Handle ------------------------------------------------ Description Retrieve the 'OCIThreadHandle' of the thread in which it is called. Prototype sword OCIThreadHandleGet(void *hndl, OCIError *err, OCIThreadHandle *tHnd); hndl(IN/OUT): The OCI environment or session handle. err(IN/OUT): The OCI error handle. If there is an error and OCI_ERROR is returned, the error is recorded in err and diagnostic information can be obtained by calling OCIErrorGet(). tHnd(IN/OUT): If not NULL, the location to place the thread handle for the thread. Returns OCI_SUCCESS, OCI_ERROR or OCI_INVALID_HANDLE. Notes 'thnd' should be initialized by OCIThreadHndInit(). The thread handle 'tHnd' retrieved by this function must be closed with OCIThreadClose() and destroyed by OCIThreadHndDestroy() after it is used. 1.4 Using OCIThread ===================== This section summarizes some of the more important details relating to the use of OCIThread. * Process initialization OCIThread only requires that the process initialization function ('OCIThreadProcessInit()') be called when OCIThread is being used in a multi-threaded application. Failing to call 'OCIThreadProcessInit()' in a single-threaded application is not an error. * OCIThread initialization Separate calls to 'OCIThreadInit()' will all return the same OCIThread context. Also, remember that each call to 'OCIThreadInit()' must eventually be matched by a call to 'OCIThreadTerm()'. * Active vs. Passive Threading primitives OCIThread client code written without using any active primitives can be compiled and used without change on both single-threaded and multi-threaded platforms. OCIThread client code written using active primitives will only work correctly on multi-threaded platforms. In order to write a version of the same application to run on single-threaded platform, it is necessary to branch the your code, whether by branching versions of the source file or by branching at runtime with the OCIThreadIsMulti() call. ******************************************************************************/ /***************************************************************************** ACTUAL PROTOTYPE DECLARATIONS ******************************************************************************/ void OCIThreadProcessInit();
