| /* |
| * Test Name: accept01 |
| * |
| * Test Description: |
| * Verify that accept() returns the proper errno for various failure cases |
| * |
| * Usage: <for command-line> |
| * accept01 [-c n] [-e] [-f] [-i n] [-I x] [-P x] [-t] |
| * where, -c n : Run n copies concurrently. |
| * -e : Turn on errno logging. |
| * -f : Turn off functionality Testing. |
| * -i n : Execute test n times. |
| * -I x : Execute test for x seconds. |
| * -P x : Pause for x seconds between iterations. |
| * -t : Turn on syscall timing. |
| * |
| * HISTORY |
| * 07/2001 Ported by Wayne Boyer |
| * |
| * RESTRICTIONS: |
| * None. |
