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