Subject: Is this possible with the Resource Manager?

If you do GetResource() for a resource that is currently in memory,
you get a Handle to the data as it appears in memory.  Is it possible,
without disturbing the resource in memory, to get the resource data
as it appears on the disk?  Something like:

	SetResLoad(FALSE);
	resHand = GetResource(type, id);
	SetResLoad(TRUE);
	if (*resHand!=NULL) {		/* The resource was loaded */
		DetatchResource(resHand);
		onDiskHand = GetResource(type, id);
		DetachResource(onDiskHand);
		ReattachResource(resHand, type, id);
		}

Would work, if the call ReattachResource() existed.  I don't think
there is any way to do this.  Any ideas?

-Eric
