Description

VixHandle
VixVM_RemoveSnapshot(VixHandle vmHandle,
                     VixHandle snapshotHandle,
                     int options,
                     VixEventProc *callbackProc,
                     void *clientData);

This function deletes all saved states for the specified snapshot.

Parameters

vmHandle
Identifies a virtual machine. Call VixVM_Open() to create a virtual machine handle.
snapshotHandle
A handle to a snapshot. Call VixVM_GetRootSnapshot() to get a snapshot handle.
options
Flags to specify optional behavior. Any combination of the following or 0:
callbackProc
A callback function that will be invoked when the operation is complete.
clientData
A parameter that will be passed to the callbackProc function.

Return Value

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

Remarks

Side Effects

None.

Requirements

vix.h, since VMware Server 1.0
