 * version of IPC should be able to interoperate TCA fully.  Client
 * programs can now link to both tca and ipc.
 *
 * Revision 2.1.1.1  1999/11/23 19:07:34  reids
 * Putting IPC Version 2.9.0 under local (CMU) CVS control.

 * Better error handling; Support for CLISP.
 *
 * Revision 1.1  1996/05/09 01:01:55  reids
 * Moved all the X_IPC files over to the IPC directory.

 * VxWorks m68k version released.
 *
 * Revision 1.1  1996/03/03 04:32:26  reids
 * First release of IPC files.  X_IPC code (8.5), modified to support NM-DS1 IPC.
 *

 * Fixed memory and other problems found with purify.
 *
 * Revision 1.7  1995/12/17  20:22:03  rich
 * Have free routines set pointers to NULL.
 * Removed old makefiles.
 *
 * Revision 1.6  1995/07/06  21:17:16  rich
 * Solaris and Linux changes.
 *
 * Revision 1.5  1995/05/31  19:36:29  rich

 * Optimize the buffer size.
 *
 * Revision 1.3  1994/05/17  23:17:21  rich
 * Added global variables and associated routines.
 * Added some error checking.  The central connection is now set to -1
 * rather than zero to prevent x_ipc messages from being send to stdout.
 * Now compiles on the sgi machines.  Still need to have the endian and
 * alignment figured out automatically.
 *
 * Revision 1.2  1993/12/01  18:04:22  rich
 * Fixed a problem with the port number being double converted to network
 * byte order.
 * Some general cleanup.
