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