1.10 + * File: sockping.c
1.11 + *
1.12 + * Description:
1.13 + * This test runs in conjunction with the sockpong test.
1.14 + * This test creates a socket pair and passes one socket
1.15 + * to the sockpong test. Then this test writes "ping" to
1.16 + * to the sockpong test and the sockpong test writes "pong"
1.17 + * back. To run this pair of tests, just invoke sockping.
1.18 + *
1.19 + * Tested areas: process creation, socket pairs, file
1.20 + * descriptor inheritance.
