FSpSetFLock

FSpSetFLock
Header:	Files.h		Carbon status:	Supported

Locks a file.

OSErr FSpSetFLock (
    const FSSpec *spec
);

spec: A pointer to an FSSpec structure specifying the file to lock.

function result: A result code.

DISCUSSION

After you lock a file, all new access paths to that file are read-only. This function has no effect on existing access paths.

If the PBHGetVolParmsSync or PBHGetVolParmsAsync functions indicate that the volume supports folder locking (that is, the bHasFolderLock bit of the vMAttrib field is set), you can use FSpSetFLock to lock a directory.

AVAILABILITY

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