| Test the error condition of calling sigdelset() to delete a signal not |
| there. |
| Test steps: |
| 1) Initialize an empty signal set. |
| 2) Verify the SIGCHLD signal is not in the empty signal set. |
| 3) Attempt to remove the SIGCHLD signal from the signal set. |
| 4) Verify the SIGCHLD signal is still not in the signal set. |
