| 21 | * NAME |
| 22 | * kill04.c |
| 23 | * |
| 24 | * DESCRIPTION |
| 25 | * Test case to check that kill() fails when passed a non-existant pid. |
| 26 | * |
| 27 | * ALGORITHM |
| 28 | * call setup |
| 29 | * loop if the -i option was given |
| 30 | * fork a child |
| 31 | * execute the kill system call with a non-existant PID |
| 32 | * check the return value |
| 33 | * if return value is not -1 |
| 34 | * issue a FAIL message, break remaining tests and cleanup |
| 35 | * if we are doing functional testing |
| 36 | * if the errno was set to 3 (No such proccess) |
| 37 | * issue a PASS message |
| 38 | * otherwise |
| 39 | * issue a FAIL message |
| 40 | * call cleanup |
| 41 | * |
| 42 | * USAGE |
| 43 | * kill04 [-c n] [-f] [-i n] [-I x] [-P x] [-t] |
| 44 | * where, -c n : Run n copies concurrently. |
| 45 | * -f : Turn off functionality Testing. |
| 46 | * -i n : Execute test n times. |
| 47 | * -I x : Execute test for x seconds. |
| 48 | * -P x : Pause for x seconds between iterations. |
| 49 | * -t : Turn on syscall timing. |
| 50 | * |
| 51 | * HISTORY |

| 53 | * |
| 54 | * RESTRICTIONS |
| 55 | * This test should be run by a non-root user |
