* File: pipepong2.c
*
* Description:
* This test runs in conjunction with the pipeping2 test.
* The pipeping2 test creates two pipes and passes two
* pipe fd's to this test. Then the pipeping2 test writes
* "ping" to this test and this test writes "pong" back.
* To run this pair of tests, just invoke pipeping2.
*
* Tested areas: process creation, pipes, file descriptor
* inheritance.
