clean_exit.c revision 311814 
1 /*
2  * clean_exit() cleans up and terminates the program. It should be called
3  * instead of exit() when for some reason the real network daemon will not or
4  * cannot be run. Reason: in the case of a datagram-oriented service we must
5  * discard the not-yet received data from the client. Otherwise, inetd will
6  * see the same datagram again and again, and go into a loop.
