 *
 * $Log: convert.c,v $
 * Revision 1.20  2006/08/08 13:23:29  keil
 * some endian fixes for BIGENDIAN systems
 *
 * Revision 1.19  2005/05/09 08:23:01  calle
 * - added SendingComplete to CONNECT_RESP (no funktions changed).
 *
 * Revision 1.18  2005/03/08 07:26:47  keil
 * - add SENDING_COMPLETE to INFO_REQ CONNECT_REQ and CONNECT_IND
 * - remove SENDING_COMPLETE parameter (always NULL) from capi_fill_DISCONNECT_REQ
 *
 * Revision 1.17  2005/03/04 11:45:12  calle
 * SendingComplete was missing for DISCONNECT_REQ ...
 *
 * Revision 1.16  2005/03/04 10:57:05  calle
 * Bugfix: CAPI_LIBRARY_V2 sone ifdef/ifndef where wrong.
 *
 * Revision 1.15  2005/02/22 11:39:43  keil
 * for backward compatibility the libcapi20 can now compiled to support the
 * old (buggy) version2 ABI. This is not for future developments. This is only
 * to support old binaries, which are linked against the old V2 lib.
 *
 * Revision 1.14  2005/02/21 17:37:07  keil
 * libcapi20 version 3.0.0
 *  - add SENDING COMPLETE in ALERT_REQ
 *  - add Globalconfiguration to CONNECT_REQ/RESP and SELECT_B_PROTOCOL_REQ
 *
 * * NOTE: incompatible to 2.X.Y versions
 *
 * Revision 1.13  2004/10/06 15:24:43  calle
 * - "SendingComplete"-Patch reverted => 2.0.8 was not binaer compartible
 * - Bugfix: capi20_register() with MaxB3Connection == 0 results in a
 *   core dump. Now at least one buffer is allocated.
 *
 * Revision 1.12  2004/06/14 11:23:48  calle
 * Erweiterungen fuer ALERT_REQ.
 *
 * Revision 1.11  2001/03/01 14:59:11  paul
 * Various patches to fix errors when using the newest glibc,
 * replaced use of insecure tempnam() function
 * and to remove warnings etc.
 *
 * Revision 1.10  2000/05/18 15:02:26  calle
 * Updated _cmsg handling added new functions need by "capiconn".
 *
 * Revision 1.9  1999/12/06 17:08:30  calle
 * - Splitted capi20.h into capi20.h and capiutils.h.
 *   - capi20.h: the functions from the CAPI-2.0 Spec
 *   - capiutils.h: the "CAPI-ADK" functions
 * - bug in 64Bit-Support fixed.
 *
 * Revision 1.8  1999/10/20 16:43:17  calle
 * - The CAPI20 library is now a shared library.
 * - Arguments of function capi20_put_message swapped, to match capi spec.
 * - All capi20 related subdirs converted to use automake.
 * - Removed dependency to CONFIG_KERNELDIR where not needed.
 *
 * Revision 1.7  1999/09/15 08:10:44  calle
 * Bugfix: error in 64Bit extention.
 *
 * Revision 1.6  1999/09/10 17:20:33  calle
 * Last changes for proposed standards (CAPI 2.0):
 * - AK1-148 "Linux Extention"
 * - AK1-155 "Support of 64-bit Applications"
 *
 * Revision 1.5  1999/09/06 17:40:07  calle
 * Changes for CAPI 2.0 Spec.
 *
 * Revision 1.4  1998/10/23 12:20:44  fritz
 * Added some missing functions.
 *
 * Revision 1.3  1998/08/30 09:57:21  calle
 * I hope it is know readable for everybody.
 *
 * Revision 1.1  1998/08/25 16:33:23  calle
 * Added CAPI2.0 library. First Version.
