| * 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. |
