* File: pipepong.c
*
* Description:
* This test runs in conjunction with the pipeping test.
* The pipeping test creates two pipes and redirects the
* stdin and stdout of this test to the pipes. Then the
* pipeping test writes "ping" to this test and this test
* writes "pong" back. Note that this test does not depend
* on NSPR at all. To run this pair of tests, just invoke
* pipeping.
*
* Tested areas: process creation, pipes, file descriptor
* inheritance, standard I/O redirection.
