 * RTCORBA.pidl,v 1.6 2003/10/28 18:29:32 bala Exp
 *
 * @brief Pre-compiled IDL source for the RTCORBA module.
 *
 * The RTCORBA module specified in CORBA v2.4.2 Chapter 24 (February,
 * 2001).
 *
 * Changes to the original OMG idl:
 *
 *     1.  Two TAO-specific interfaces, UnixDomainProtocolProperties
 *         and SharedMemoryProtocolProperties, have been added to allow
 *         configuration of TAO's UIOP and SHMEM pluggable protocols
 *         through RTCORBA Protocol Policies.
 *     2.  TAO-specific support for named mutexes has been added.
 *     3.  Added RT_ORB::create_tcp_protocol_properties which seems
 *         to come and go from the formal specification, but is needed.
 *
 *   This file was used to generate the code in RTCORBAC.{h,i,cpp}.
 *   The steps to regenerate the code are as follows:
 *
 *   1. Run the tao_idl compiler on the pidl file.  The command used for
 *   this is:
 *
 *     tao_idl -o orig -Gp -Gd -Ge 1 -GT
 *          -Wb,export_macro=TAO_RTCORBA_Export
 *          -Wb,export_include="tao/RTCORBA/rtcorba_export.h"
 *          -Wb,pre_include="ace/pre.h"
 *          -Wb,post_include="ace/post.h"
 *          RTCORBA.pidl
 *
 *   2. Then apply the patches in tao/RTCORBA/diffs to the generated code.
 *   The patches provide the following fixes: 1) remove several unnecessary
 *   includes, e.g., corba.h, stream.h, Policy.h, 3) add anything else we
 *   need into the namespace, i.e., TAO_Priority_Mapping, and 4) fix
 *   "nested_class" occurrences in the .cpp.
 *
 * Apply patches using the following commands:
 *
 *   patch < diffs/RTCORBA.diff
 *
 * Note: The diffs were generated with these commands:
 *
 *   for i in RTCORBAC.{h,i,cpp}; do
 *     diff -wBbu orig/$i $i
 *   done > diffs/RTCORBA.diff
 *
