 * directory structure shifting
 *
 * Revision 1.3  2002/03/11 19:17:10  josh
 * snmptalk's destination address is now stored and passed around
 * as an ipaddr_t.  This required changes to a lot of internal function
 * calls that used to expect an inaddr_t to be passed around.  Also,
 * snmptalk is now capable of using IPv6 sockets
 *
 * Revision 1.2  2001/11/08 16:47:31  tneale

 *
 * Revision 7.13  1998/06/07 02:51:40  sar
 * Move the validate routines to snark library, leaving

 *
 * Revision 7.12  1998/06/04 15:13:50  sar

 *
 * Revision 7.4  1997/01/09 22:44:19  sar

 *
 * Revision 6.3  1996/01/10  16:41:40  sar
 * Usec updates
 *
 * Revision 6.2  1995/10/20  22:39:59  sar

 * Updated the GET and NEXT commands to take multiple arguments.
 *
 * Revision 6.0  1995/05/31  21:50:23  sra
 * Release 6.0.
 *
 * Revision 5.5  1994/11/09  01:43:52  sar
 * Read the nv config file if/when we need to.  If the master_agent or
 * v2_view options are installed we always read it, if they aren't vut
 * v2 is installed we check the snmptalk_version flag if it is 2 we read
 * the file if it is 1 we don't.  The first time we switch to v2 we
 * try and read the file and complain if one doesn't exist.  If we only
 * have v1 installed we never read the config file.
 *
 * Revision 5.4  1994/10/28  19:50:09  sar
 * Modifed error flags, authorization error shouldn't have vbs.
 * Also added a test in the error print routine so that we don't try and
 * print out vbs < 1 (1 is the lowest index).
 *
 * Revision 5.3  1994/09/29  18:33:21  sar
 * Only include & use v2 types if necessary (v2 or use_v2_types installed).
 *
 * Revision 5.2  1994/09/23  19:29:50  sar
 * Removed the old non volatile scheme and added a new one that is hopefully
 * easier to use and allows for some new options such as a read only
 * flag to prohibit creating a new config file.  The config stuff will
 * only be included if needed.
 * In snmptalk and snmpint added a next function.
 *
 * Revision 5.1  1994/07/24  15:41:03  dab
 * Added ability to set UDP port used by manager and the set command can
 * now specify enumerated integer values by symbolic name.
 *
 * Revision 5.0  1994/05/16  15:57:40  sar
 * Updated revision to 5.0 and copyright to include 1994
 *
 * Revision 4.8  1994/05/13  21:52:39  sar
 * When writing out the version stamp for party database config files use
 * a long as the version is 32 bits.
 *
 * Revision 4.7  1994/05/12  17:20:45  sar
 * We were doing snmp_view_config twice in some cases so I removed one of
 * the calls.
 *
 * Revision 4.6  1994/05/11  17:57:30  sar
 * added master_agent as a reason to include snmptalk_view_init.
 *
 * Revision 4.5  1994/05/09  20:59:43  sar
 * Added SNMPTalk_View_Init for use with USE_V2_VIEWS option (so we can
 * install a v2 view without installing the rest of the v2 database.
 *
 * Revision 4.4  1994/04/29  20:21:12  sar
 * Added a line to set the view_index to 1 while validating the community.
 * This probably should be upgraded at some time to allow a dynamic choice.
 *
 * Revision 4.3  1993/11/12  19:41:28  sar
 * Removed some unnecessary & from in front of the set_state->bstring var.
 *
 * Revision 4.2  1993/10/06  19:45:35  sar
 * Added more flags to snmp_errors_flags to handle the snmp v2 cases.
 *
 * Revision 4.1  1993/10/05  17:13:12  sar
 * Modified the handling of parsing a bit string to check for char 1 instead
 * of int 1.  Also adjusted the argument counter and pointers in tset to
 * get the right info to parse_bitstring.
 *
 * Revision 4.0  1993/06/24  17:14:56  sar
 * Updated rev to 4.0 and copyright to 93
 *

 * being there.
 *
 * Revision 3.37  1993/06/13  02:48:16  sar
 * moved inclusion of stdf.h to be after asn1.h so that NO_PP will be defined
 * if desired.
 *
 * Revision 3.36  1993/06/02  23:10:22  dab
 * Changed #ifdef's to #if's for things from install.h
 *
 * Revision 3.35  1993/05/31  19:07:48  sar
 * use fprintf rather than fwrite to output the version stamps for
 * the v2 config files.  Also changed the call to acl_nvwrite to have
 * the source, dest in the correct order.
 *
 * Revision 3.34  1993/05/29  00:18:57  sar
 * swapped the sparty and dparty args to snmp_acl_install

 * partyauthclock as the string.
 *
 * Revision 3.32  1993/05/22  01:09:35  sar
 * Cleaned up some ifdefs of snmpstats and bulk usage so we can compile
 * with out stats and in v1 mode.
 *
 * Revision 3.31  1993/05/20  20:34:22  sar
 * tidied up some fprintf commands.
 *
 * Revision 3.30  1993/05/19  20:38:22  sar

 *
 * Revision 3.23  1993/05/03  17:08:45  sar
 * modified do_bulk to allocate the memory it needs for oids rather than using
 * stack based area.  This makes the stack smaller and avoided a stack overflow
 * condition elsewhere.
 *
 * Revision 3.22  1993/04/30  23:01:50  sar
 * modified the sync_print routine to use the lockable version of timestamp
 * routines.
 *
 * Revision 3.21  1993/04/26  20:30:09  sar
 * Added ifdefs (and corrected code) to allow clean makes of version 1 or 2
 *
 * Revision 3.20  1993/04/23  23:37:54  sar
 * Collected objectid defines in one file (wkobj.h) and modified do_bulk

 * Updated to use the new OIDC_T/length version of the SNMP_(Party, Context)_*
 * calls.  Also updated to use the new acl routines.
 *
 * Revision 3.7  1993/02/23  19:02:01  dab

 * Added SNMPTalk_Party_Init().
 *
 * Revision 3.6  1993/02/22  20:56:25  dab

 * both v1 and v2.
 *
 * Revision 3.5  1993/02/18  20:42:13  sar

 * number of non-repeaters, the max reps and some oids to form into a pkt.
 *
 * Revision 3.1  92/06/16  16:05:44  dab
 * Added batch mode
 *

 * Revision 2.114  91/12/12  09:40:58  dab
 * Changed to use "nprint.h" instead of <print.h>.
 * 
 * Revision 2.113  91/12/10  10:50:43  dab
 * Errors now print which varbind got the error.
 *

 * if there were no errors and didn't print the error if there was.
 * 
 * Revision 2.109  91/11/04  18:56:36  dab
 * Improved the set command to take multiple arguments to set in a 
 * single packet.  Also fixed the setting of IP addresses which was
 * broken when md_hostname_to_addr went async.
 * 
 * Revision 2.108  91/11/04  16:15:08  dab
 * Improved for use with higher warning levels on the compiler.
 * 
 * Revision 2.107  91/11/03  10:19:45  dab

 * 
 * Revision 2.106  91/10/30  09:40:47  dab
 * Disabled setting of IP addresses for now because of change of
 * interface of md_hostname_to_addr to an async one.
 * 
 * Revision 2.105  91/10/30  09:22:10  dab
 * Don't do commands if destination isn't set.

 * 
 * Revision 2.102  91/09/12  13:46:14  dab
 * No, this contains the changes for asynchronous environments.
 * 
 * Revision 2.100  91/08/09  14:05:25  dab
 * Update version number.  This is just before the work to upgrade to
