on_config_exit.rs

/*on config On_config_listen_exit is another function
 with same parameters as of On_config_listen_enter,
  but returns 0 or -1, depending on the success of 
  the function call execution. If number of host 
  listening on that particular configurator is 0,
 and number of global listener is also 0, then it
 will print “mandatory configuration directive is missing”
  and returns -1
