VixHost_FindItems

Description

VixHandle
VixHost_FindItems(VixHandle hostHandle,
                  VixFindItemType searchType,
                  VixHandle searchCriteria,
                  int32 timeout,
                  VixEventProc *callbackProc,
                  void *clientData);

This function asynchronously finds Vix objects and calls the application's callback function to report each object found. For example, when used to find all running virtual machines, VixHost_FindItems() returns a series of virtual machine file path names.

Parameters

hostHandle
The host handle returned by VixHost_Connect().
searchType
The type of items to find. Values are listed in the Types Reference under VixFindItemType.
searchCriteria
Must be VIX_INVALID_HANDLE.
timeout
Must be -1.
callbackProc
A function to be invoked when VixHost_FindItems() completes.
clientData
A user-supplied parameter to be passed to the callback function.

Return Value

VixHandle. A job handle that describes the state of this asynchronous call.

Remarks

Side Effects

None.

Requirements

vix.h, since VMware Server 1.0.

Example

The following example prints the path name of every virtual machine currently running on the host.
static VixHandle hostHandle = VIX_INVALID_HANDLE;

void VixDiscoveryProc(VixHandle jobHandle,
                      VixEventType eventType,
                      VixHandle moreEventInfo,
                      void *clientData)
{
   VixError err = VIX_OK;
   char *url = NULL;

   // Check callback event; ignore progress reports.
   if (VIX_EVENTTYPE_FIND_ITEM != eventType) {
      return;
   }

   // Found a virtual machine.
   err = Vix_GetProperties(moreEventInfo,
                           VIX_PROPERTY_FOUND_ITEM_LOCATION,
