/*
|
|
* 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.
