Resource Manager Routines

Getting a Unique Resource ID

The Resource Manager provides two routines that return a unique resource ID. The UniqueID function returns a resource ID that isn't currently assigned to any resource of the specified type in any open resource fork. The Unique1ID function returns a resource ID that isn't currently assigned to any resource of the specified type in the resource fork of the current resource file.
