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