Resource Manager Routines

Disposing of Resources

The Resource Manager provides three procedures for disposing of resources. The ReleaseResource procedure releases the memory associated with a resource,
setting the handle's master pointer to NIL, thus making your application's handle to
the resource invalid. The DetachResource procedure sets a resource's handle in the resource map to NIL but keeps the resource data in memory. The RemoveResource procedure removes the resource's entry from the resource map in memory; the
Resource Manager removes the resource data from memory (and from the file's resource fork) when it updates the file's resource fork.
