|
|
** 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.
|
|
