vRefNum
A volume reference number, a working directory reference number, or 0 for the default volume.

DESCRIPTION
The HRstFLock function unlocks a file.
If the PBHGetVolParms function indicates that the volume supports folder locking (that is, the bHasFolderLock bit of the vMAttrib field is set), you can use HRstFLock to unlock a directory.
