michael@0:  * Description:
michael@0:  * This test runs in conjunction with the sockpong test.
michael@0:  * This test creates a socket pair and passes one socket
michael@0:  * to the sockpong test.  Then this test writes "ping" to
michael@0:  * to the sockpong test and the sockpong test writes "pong"
michael@0:  * back.  To run this pair of tests, just invoke sockping.
michael@0:  *
michael@0:  * Tested areas: process creation, socket pairs, file
michael@0:  * descriptor inheritance.
