/*
* $Log: vbdefs.h,v $
* Revision 1.3 2002/05/13 20:46:19 josh
* encoding process now checks for 16-bit overflows in
* calculating packet sizes
*
* Revision 1.2 2001/11/06 21:35:07 josh
* new revised path structure, first pass. Also removing useless
* shell include files.
*
* Revision 1.1.1.1 2001/11/05 17:47:24 tneale
* Tornado shuffle
*
* Revision 9.7 2001/01/19 22:22:13 paul
* Update copyright.
*
* Revision 9.6 2000/03/17 19:48:48 meister
* Update copyright notice
*
* Revision 9.5 2000/03/09 20:58:37 tneale
* All structure definitions are now bracketted with a test that
* potentially sets an alignment pragma. This is to maintain compatibility
* with the code base that had been distributed by Wind River.
*
* Revision 9.4 2000/03/09 17:14:20 tneale
* Added #ifdef for C++ to extern C if needed
*
* Revision 9.3 2000/02/02 17:35:28 josh
* adding VBList_Free() API call
*
* Revision 9.2 1999/12/23 14:47:28 josh
* cleaning up code per Shawn's comments -- removing extraneous
* comments and doing proxy check before notify check
*
* Revision 9.1 1999/05/24 20:12:12 josh
* 'compc' and 'compl' have been replaced by 'tcount' and 'tlist'
* to avoid C++ compiler errors.
*
* Revision 9.0 1998/10/16 22:10:28 sar
* Update version stamp to match release
*
* Revision 8.1 1998/02/25 04:50:54 sra
* Update copyrights.
*
* Revision 8.0 1997/11/18 00:56:33 sar
* Updated revision to 8.0
*
* Revision 7.6 1997/10/26 01:44:43 sar
* Always define the 64 bit counter and include it in the vb defintion
* instead of forgetting about it if we don't have v2 or v2 types installed.
*
* Revision 7.5 1997/10/22 03:07:28 sar
* Mofied the agentx and older subagent schemes install options
*
* Revision 7.4 1997/10/16 23:52:27 sar
* We changed the macro VB_GET_IP_ADDRESS to provide a more consistent
* type signature from compilers. Previously it could have been either
* a pointer to an array of bytes or a pointer to a byte. It should
* now resolve to a pointer to an array of bytes.
*
* Revision 7.3 1997/10/16 00:25:19 sar
* Primarily this set of modifications is for the agentx protocol.
* Most of the work was in the agentx.h and ax_mth.h files. Most
* other files (snmpdefs.h, vbdefs.h and mib.h) received updates
* to their structures and snmp got some new lock macros.
*
* One other change of note was the modification of continue
* processing. Previously we called a specific continue routine
* directly, now we store a pointer to the corret continue
* function in the snmp packet structure and call that. We include
* macros for backwards compatibility.
*
* Revision 7.2 1997/03/20 06:48:25 sra
* DFARS-safe copyright text. Zap!
*
* Revision 7.1 1997/02/25 10:49:26 sra
* Update copyright notice, dust under the bed.
*
* Revision 7.0 1996/03/18 20:17:33 sar
* Updated rev to 7.0 and copyright to 96
*
* Revision 6.2 1995/10/20 22:53:35 sar
* removed bitstring include file & macro
* removed nsapaddress
* added VT_BITS & VT_UNSIGNED32
*
* Revision 6.1 1995/06/05 20:57:49 sar
* Added clean_vb_data.
*
* Revision 6.0 1995/05/31 21:46:57 sra
* Release 6.0.
*
* Revision 1.1 1995/03/20 23:07:47 sar
* Initial revision
