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