			<** The parameter is an optional output. If it is not a

/*****************************************************************************/

#pragma mark FSDeleteFileIDRef

/*
	Why is there no FSDeleteFileIDRef routine? There are two reasons:
	
	1.	Since Mac OS 8.1, PBDeleteFileIDRef hasn't deleted file ID references.
		On HFS volumes, deleting a file ID reference breaks aliases (which
		use file ID references to track files as they are moved around on a
		volume) and file ID references are automatically deleted when the file
		they refer to is deleted. On HFS Plus volumes, file ID references are
		always created when a file is created, deleted when the file is deleted,
		and cannot be deleted at any other time.
		
	2.	PBDeleteFileIDRef causes a memory access fault under Mac OS X 10.0
		through 10.1.x. While this will be fixed in a future release, the
		implementation, like the Mac OS 8/9 implementation, does not delete
		file ID references.
