/*
|
|
* 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.
