Diagnostics

If TipcSrvDefaultCbLookup fails, it returns NULL and sets the global SmartSockets error number to one of:

Description

TipcSrvDefaultCbLookup looks up a default callback with the desired function and argument in the connection to RTserver by calling TipcConnDefaultCbLookup. These callbacks are called by TipcSrvMsgProcess when there are no process callbacks for the type of message being processed. See TipcConnDefaultCbCreate for more information on default callbacks.

TipcSrvDefaultCbLookup may attempt to automatically create a connection to RTserver. If RTclient has a warm connection to RTserver, TipcSrvDefaultCbLookup looks up a default callback in the warm connection. See TipcSrvCreate for information on automatic creation of connections and warm connections to RTserver.

Caution

None

Examples

This looks up and destroys a default callback in the connection to RTserver:

cb = TipcSrvDefaultCbLookup(my_srv_default_cb, NULL); 
if (cb == NULL) { 
  return;  /* error */ 
}  
if (!TutCbDestroy(cb)) { 
  return;  /* error */ 
}
