8 * Revision 1.12 1999-04-20 10:01:46 adam
9 * Modified calls to ODR encoders/decoders (name argument).
11 * Revision 1.11 1996/07/03 13:31:14 adam
12 * The xmalloc/xfree functions from YAZ are used to manage memory.
14 * Revision 1.10 1996/06/03 09:04:24 adam
15 * Changed a few logf calls.
17 * Revision 1.9 1996/03/20 13:54:05 adam
18 * The Tcl_File structure is only manipulated in the Tk-event interface
21 * Revision 1.8 1996/03/05 09:21:20 adam
22 * Bug fix: memory used by GRS records wasn't freed.
23 * Rewrote some of the error handling code - the connection is always
24 * closed before failback is called.
25 * If failback is defined the send APDU methods (init, search, ...) will
26 * return OK but invoke failback (as is the case if the write operation
28 * Bug fix: ref_count in assoc object could grow if fraction of PDU was
31 * Revision 1.7 1996/02/19 15:41:55 adam
