| 23 | * DESCRIPTION |
DAN LI | bffa886 | 2013-05-13 10:21:43 +0800 | [diff] [blame] | 24 | * semctl01 - test the 13 possible semctl() commands |
plars | 865695b | 2001-08-27 22:15:12 +0000 | [diff] [blame] | 25 | * |
| 26 | * ALGORITHM |
| 27 | * create a semaphore set with read and alter permissions |
| 28 | * loop if that option was specified |
| 29 | * loop through the test cases |
| 30 | * do any setup required for the test case |
| 31 | * make the semctl() call using the TEST() macro |
| 32 | * check the return code |
| 33 | * if failure, issue a FAIL message. |
| 34 | * otherwise, |
| 35 | * if doing functionality testing |
| 36 | * call the appropriate test function |
DAN LI | bffa886 | 2013-05-13 10:21:43 +0800 | [diff] [blame] | 37 | * if correct, |
plars | 865695b | 2001-08-27 22:15:12 +0000 | [diff] [blame] | 38 | * issue a PASS message |
| 39 | * otherwise |
| 40 | * issue a FAIL message |
| 41 | * call cleanup |
