+/*******************************************************************
+** udpsrc.c -- Test basic function of UDP server
+**
+** udpsrv operates on the same machine with program udpclt.
+** udpsrv is the server side of a udp sockets application.
+** udpclt is the client side of a udp sockets application.
+**
+** The test is designed to assist developers in porting/debugging
+** the UDP socket functions of NSPR.
+**
+** This test is not a stress test.
+**
+** main() starts two threads: UDP_Server() and UDP_Client();
+** main() uses PR_JoinThread() to wait for the threads to complete.
+**
+** UDP_Server() does repeated recvfrom()s from a socket.
+** He detects an EOF condition set by UDP_Client(). For each
+** packet received by UDP_Server(), he checks its content for
+** expected content, then sends the packet back to UDP_Client().
+**
+** UDP_Client() sends packets to UDP_Server() using sendto()
+** he recieves packets back from the server via recvfrom().
+** After he sends enough packets containing UDP_AMOUNT_TO_WRITE
+** bytes of data, he sends an EOF message.
+**
+** The test issues a pass/fail message at end.
+**
+** Notes:
+** The variable "_debug_on" can be set to 1 to cause diagnostic
+** messages related to client/server synchronization. Useful when
+** the test hangs.
+**
+** Error messages are written to stdout.
