| 21 | * NAME |
| 22 | * signal02.c |
| 23 | * |
| 24 | * DESCRIPTION |
| 25 | * signal02 - Test that we get an error using illegal signals |
| 26 | * |
| 27 | * ALGORITHM |
| 28 | * loop if that option was specified |
| 29 | * issue the system call |
| 30 | * check the return value |
| 31 | * if return value != -1 |
| 32 | * issue a FAIL message, break remaining tests and cleanup |
| 33 | * if we get an EINVAL |
| 34 | * issue a PASS message |
| 35 | * else |
| 36 | * issue a FAIL message, break remaining tests and cleanup |
| 37 | * call cleanup |
| 38 | * |
| 39 | * USAGE: <for command-line> |
| 40 | * signal02 [-c n] [-e] [-i n] [-I x] [-p x] [-t] |
| 41 | * where, -c n : Run n copies concurrently. |
| 42 | * -e : Turn on error logging. |
| 43 | * -i n : Execute test n times. |
| 44 | * -I x : Execute test for x seconds. |
| 45 | * -P x : Pause for x seconds between iterations. |
| 46 | * -t : Turn on syscall timing. |
