GetVolumeNameForVolumeMountPointW
@implemented Return an unique volume name for a drive root or mount point. Parameters VolumeMountPoint Pointer to string that contains either root drive name or mount point name. VolumeName Pointer to buffer that is filled with resulting unique volume name on success. VolumeNameLength Size of VolumeName buffer in TCHARs. Returns TRUE when the function succeeds and the VolumeName buffer is filled, FALSE otherwise.
