Unlocks a file.

OSErr HRstFLock (
    SInt16 vRefNum, 
    SInt32 dirID, 
    ConstStr255Param fileName
);

Parameter descriptions

vRefNum

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

dirID

A directory ID.

fileName

The name of the file.

function result

A result code.

DISCUSSION

If the PBHGetVolParmsSync or PBHGetVolParmsAsync 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.

AVAILABILITY

Supported in Carbon. Available in Carbon 1.0.2 and later when running Mac OS 8.1 or later.
