+ * 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.
