5 * $Log: yaz-z-assoc.cpp,v $
6 * Revision 1.18 2001-03-26 14:43:49 adam
7 * New threaded PDU association.
9 * Revision 1.17 2001/01/04 14:25:25 heikki
10 * No SIGPIPES in windows...
12 * Revision 1.16 2000/12/14 16:00:39 adam
13 * Ignoring signal SIGPIPE.
15 * Revision 1.15 2000/10/11 11:58:17 adam
16 * Moved header files to include/yaz++. Switched to libtool and automake.
17 * Configure script creates yaz++-config script.
19 * Revision 1.14 2000/09/12 16:40:33 heikki
22 * Revision 1.13 2000/09/08 10:23:42 adam
23 * Added skeleton of yaz-z-server.
25 * Revision 1.12 2000/09/05 13:57:28 adam
26 * Fixed get_otherInfoAPDU to return otherInfo for extended services.
28 * Revision 1.11 2000/09/04 08:59:16 adam
29 * Changed call to logging functions (yaz_ added).
31 * Revision 1.10 2000/09/04 08:29:22 adam
32 * Fixed memory leak(s). Added re-use of associations, rather than
33 * re-init, when maximum number of targets are in use.
35 * Revision 1.9 2000/08/10 08:42:42 adam
36 * Fixes for {set,get}_APDU_log.
38 * Revision 1.8 2000/08/07 14:19:59 adam
39 * Fixed serious bug regarding timeouts. Improved logging for proxy.
41 * Revision 1.7 2000/05/10 11:36:58 ian
42 * Added default parameters for refid to request functions.
43 * Added default parameter for result set name to search and present request.
44 * Commented out forced logging of PDU contents.
45 * Added send_deleteResultSetRequest
47 * Revision 1.6 1999/12/06 13:52:45 adam
48 * Modified for new location of YAZ header files. Experimental threaded
51 * Revision 1.5 1999/11/10 10:02:34 adam
54 * Revision 1.4 1999/09/13 12:53:44 adam
55 * Proxy removes OtherInfo Proxy Address and Session ID. Other
56 * Otherinfo remains untouched.
58 * Revision 1.3 1999/04/21 12:09:01 adam
59 * Many improvements. Modified to proxy server to work with "sessions"
62 * Revision 1.2 1999/04/20 10:30:05 adam
63 * Implemented various stuff for client and proxy. Updated calls
64 * to ODR to reflect new name parameter.
66 * Revision 1.1 1999/04/09 11:46:57 adam
67 * Added object Yaz_Z_Assoc. Much more functional client.
