| * This sample test aims to check the following assertion: |
| * |
| * sem_unlink will return -1 and set errno to ENOENT when the named semaphore |
| * does not exist. |
| |
| * The steps are: |
| * -> Unlink once to make sure this name does not exist. Ignore the error. |
| * -> Unlink again and check that ENOENT is returned |
| |
| * The test fails if the error is not ENOENT, or there is no error. |
