- * Revision 1.14 88/01/14 13:14:37 mar
- * 1. separate access checking from setup routines
- * 2. check max argument length
- *
- * Revision 1.13 88/01/04 12:02:13 mar
- * moved transaction start before pre-routines (wesommer)
- *
- * Revision 1.13 87/11/12 18:13:12 wesommer
- * Move transaction boundary to include the pre routine.
- *
- * Revision 1.12 87/09/12 20:42:11 wesommer
- * Clean up after Gretzinger: cl->kname is not valid unless cl->clname is
- * non-NULL.
- *
- * Revision 1.12 87/09/12 20:06:46 wesommer
- * Fix security hole/null dereference bug: if clname is NULL, return
- * permission denied in get_client.
- *
- * Revision 1.11 87/09/01 16:10:01 wesommer
- * This change was made by Mike, who didn't feel like checking it in.
- * Temp hack: ignore instances.
- *
- * Revision 1.10 87/08/28 14:57:51 mike
- * Modified sms_query to not enclose RETRIEVE queries in begin/end transaction.
- * This was necessary to allow get_all_poboxes and get_groups_of_all_users
- * to temporarily change the Ingres lockmode.
- *
- * Revision 1.9 87/08/22 17:47:38 wesommer
- * Cleanup (these changes were by Mike).
- *
- * Revision 1.8 87/08/10 16:22:26 mike
- * wesommer modified error reporting.
- *
- * Revision 1.7 87/08/04 01:49:20 wesommer
- * Rearranged messages.
- *
- * Revision 1.6 87/08/04 01:30:54 wesommer
- * Mike's changes; checked in prior to working over messages.
- *
- * Revision 1.5 87/06/21 16:37:58 wesommer
- * Changed include files, reindented things.
- *
- *
- * Revision 1.4 87/06/08 05:03:27 wesommer
- * Reindented; added header and trailer.
