Module Name:

    Cluster registry apis.

Abstract:

    Determines whether ClusterReg or Reg apis should be used.

    The printer information is stored in the registry.  When we access
    local printers, we hit the local registry; when we access cluster
    printers, we hit the cluster registry.

Author:

    Albert Ting (AlbertT) 8-Oct-96

Environment:

    User Mode -Win32

Revision History:

    Felix Maxa (amaxa) 18-Jun-2000
       Added ClusterGetResourceID
