PBUnshare

You can use the PBUnshare function to reverse the effects of PBShare.

FUNCTION PBUnShare (paramBlock: HParmBlkPtr; async: Boolean):
                      OSErr;

paramBlock

A pointer to a basic HFS parameter block.

async

A Boolean value that specifies asynchronous (TRUE) or synchronous (FALSE) execution.

-->	ioCompletion	ProcPtr	A pointer to a completion routine.
<--	ioResult	OSErr	The result code of the function.
-->	ioNamePtr	StringPtr	A pointer to a pathname.
-->	ioVRefNum	Integer	A volume specification.
-->	ioDirID	LongInt	A directory ID.

DESCRIPTION

The PBUnshare function makes the share point specified by the ioNamePtr and ioDirID fields unavailable on the network. If ioNamePtr is NIL, then ioDirID is
the directory ID of the directory that is to become unavailable. If ioNamePtr points
to a partial pathname, ioDirID is the parent directory of the directory to become unavailable. The ioVRefNum field can contain a volume reference number, a working directory reference number, a drive number, or 0 for the default volume.
