PrlDisk_GetSnapshotsCount Function

Determines the number of snapshots of the specified virtual disk.

Syntax

PRL_RESULT PrlDisk_GetSnapshotsCount(
    const PRL_HANDLE Handle, 
    PRL_UINT32_PTR SnapshotsCount
);

File

PrlDisk.h

Parameters

Handle

A handle of type PHT_VIRTUAL_DISK identifying the virtual disk.

SnapshotsCount

[out] A pointer to a variable that receives the snapshot count.

Returns

PRL_RESULT . Possible values:

PRL_ERR_INVALID_ARG - invalid argument values.

PRL_ERR_SUCCESS - function completed successfully.

Remarks

A virtual disk snapshot is created when a snapshot of a virtual machine is created or manually using the PrlDisk_CreateState function. Snapshots of a given virtual disk are organized into a tree. You can use the PrlDisk_GetSnapshotsTree function to obtain the entire tree and then, knowing the total snapshot count, traverse the tree. Each snapshot is identified using a universally unique ID (UUID). When you know the UUID of a snapshot of interest, you can revert to it or delete it if needed.
