  * $Log: ir-tclp.h,v $
- * Revision 1.26  1996-02-21 10:16:20  adam
+ * Revision 1.33  1996-07-03 13:31:13  adam
+ * The xmalloc/xfree functions from YAZ are used to manage memory.
+ *
+ * Revision 1.32  1996/03/20  13:54:05  adam
+ * The Tcl_File structure is only manipulated in the Tk-event interface
+ * in tkinit.c.
+ *
+ * Revision 1.31  1996/03/05  09:21:19  adam
+ * Bug fix: memory used by GRS records wasn't freed.
+ * Rewrote some of the error handling code - the connection is always
+ * closed before failback is called.
+ * If failback is defined the send APDU methods (init, search, ...) will
+ * return OK but invoke failback (as is the case if the write operation
+ * fails).
+ * Bug fix: ref_count in assoc object could grow if fraction of PDU was
+ * read.
+ *
+ * Revision 1.30  1996/02/29  15:30:23  adam
+ * Export of IrTcl functionality to extensions.
+ *
+ * Revision 1.29  1996/02/26  18:38:33  adam
+ * Work on export of set methods.
+ *
+ * Revision 1.28  1996/02/23  17:31:41  adam
+ * More functions made available to the wais tcl extension.
+ *
+ * Revision 1.27  1996/02/23  13:41:41  adam
+ * Work on public access to simple ir class system.
+ *
+ * Revision 1.26  1996/02/21  10:16:20  adam
  * Simplified select handling. Only one function ir_tcl_select_set has
  * to be externally defined.
