/*
|
|
* File: pipeping.c
|
|
*
|
|
* Description:
|
|
* This test runs in conjunction with the pipepong test.
|
|
* This test creates two pipes and redirects the stdin and
|
|
* stdout of the pipepong test to the pipes. Then this
|
|
* test writes "ping" to the pipepong test and the pipepong
|
|
* test writes "pong" back. To run this pair of tests,
|
|
* just invoke pipeping.
|
|
*
|
|
* Tested areas: process creation, pipes, file descriptor
|
|
* inheritance, standard I/O redirection.
