4 * @file Codeset_Registry.h
6 * ACE wrapper around access functions for the OSF's DCE codeset registry
7 * access functions
9 * For environments that intrinsically support the DCE defined access functions,
10 * the methods in this class are simply wrappers. On other platforms, emulation
11 * is provided. The motivation for this class is to support interoperability
12 * via translators and the CDR streams, primarily in TAO, but this capability
13 * is not restricted to CORBA.
15 * The emulated functionality supports Open Group RFC #40, currently RFC 40.2,
16 * www.opengroup.org/tech/rfc/rfc40.2.html
18 * @author Phil Mesnier <mesnier_p@ociweb.com>
