| 7 * File: sockping.c | |
| 8 * | |
| 9 * Description: | |
| 10 * This test runs in conjunction with the sockpong test. | |
| 11 * This test creates a socket pair and passes one socket | |
| 12 * to the sockpong test. Then this test writes "ping" to | |
| 13 * to the sockpong test and the sockpong test writes "pong" | |
| 14 * back. To run this pair of tests, just invoke sockping. | |
| 15 * | |
| 16 * Tested areas: process creation, socket pairs, file | |
| 17 * descriptor inheritance. | |
