| * Test Name: sockioctl01 |
| * |
| * Test Description: |
| * Verify that ioctl() on sockets returns the proper errno for various |
| * failure cases |
| * |
| * Usage: <for command-line> |
| * sockioctl01 [-c n] [-e] [-i n] [-I x] [-p x] [-t] |
| * where, -c n : Run n copies concurrently. |
| * -e : Turn on errno logging. |
| * -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 John George |
| * -Ported |
| * |
| * Restrictions: |
| * None. |
