1.10 + * File: pipeping.c
1.11 + *
1.12 + * Description:
1.13 + * This test runs in conjunction with the pipepong test.
1.14 + * This test creates two pipes and redirects the stdin and
1.15 + * stdout of the pipepong test to the pipes. Then this
1.16 + * test writes "ping" to the pipepong test and the pipepong
1.17 + * test writes "pong" back. To run this pair of tests,
1.18 + * just invoke pipeping.
1.19 + *
1.20 + * Tested areas: process creation, pipes, file descriptor
1.21 + * inheritance, standard I/O redirection.
