+ * Revision 1.33 2000-09-04 08:27:11 adam
+ * Work on error handling for tcpip_accept.
+ *
+ * Revision 1.32 1999/11/30 13:47:11 adam
+ * Improved installation. Moved header files to include/yaz.
+ *
+ * Revision 1.31 1999/04/29 07:31:23 adam
+ * Changed tcpip_strtoaddr_ex so that only part 'till '/' is considered
+ * part of hostname.
+ *
+ * Revision 1.30 1999/04/20 09:56:48 adam
+ * Added 'name' paramter to encoder/decoder routines (typedef Odr_fun).
+ * Modified all encoders/decoders to reflect this change.
+ *
+ * Revision 1.29 1999/04/16 14:45:55 adam
+ * Added interface for tcpd wrapper for access control.
+ *
+ * Revision 1.28 1999/03/31 11:11:14 adam
* Function getprotobyname only called once. Minor change in tcpip_get
* to handle multi-threaded conditions.
