6 * Revision 1.16 2000-12-14 16:00:39 adam
7 * Ignoring signal SIGPIPE.
9 * Revision 1.15 2000/10/11 11:58:17 adam
10 * Moved header files to include/yaz++. Switched to libtool and automake.
11 * Configure script creates yaz++-config script.
13 * Revision 1.14 2000/09/12 16:40:33 heikki
16 * Revision 1.13 2000/09/08 10:23:42 adam
17 * Added skeleton of yaz-z-server.
19 * Revision 1.12 2000/09/05 13:57:28 adam
20 * Fixed get_otherInfoAPDU to return otherInfo for extended services.
22 * Revision 1.11 2000/09/04 08:59:16 adam
23 * Changed call to logging functions (yaz_ added).
25 * Revision 1.10 2000/09/04 08:29:22 adam
26 * Fixed memory leak(s). Added re-use of associations, rather than
27 * re-init, when maximum number of targets are in use.
29 * Revision 1.9 2000/08/10 08:42:42 adam
30 * Fixes for {set,get}_APDU_log.
32 * Revision 1.8 2000/08/07 14:19:59 adam
33 * Fixed serious bug regarding timeouts. Improved logging for proxy.
35 * Revision 1.7 2000/05/10 11:36:58 ian
36 * Added default parameters for refid to request functions.
37 * Added default parameter for result set name to search and present request.
38 * Commented out forced logging of PDU contents.
39 * Added send_deleteResultSetRequest
41 * Revision 1.6 1999/12/06 13:52:45 adam
42 * Modified for new location of YAZ header files. Experimental threaded
45 * Revision 1.5 1999/11/10 10:02:34 adam
48 * Revision 1.4 1999/09/13 12:53:44 adam
49 * Proxy removes OtherInfo Proxy Address and Session ID. Other
50 * Otherinfo remains untouched.
52 * Revision 1.3 1999/04/21 12:09:01 adam
53 * Many improvements. Modified to proxy server to work with "sessions"
56 * Revision 1.2 1999/04/20 10:30:05 adam
57 * Implemented various stuff for client and proxy. Updated calls
58 * to ODR to reflect new name parameter.
60 * Revision 1.1 1999/04/09 11:46:57 adam
61 * Added object Yaz_Z_Assoc. Much more functional client.
