| Test case for assertion #3 of the sigaction system call that shows |
| calling sigaction with a null act argument does not change the |
| signal handler. |
| |
| Steps: |
| 1. Initialize global variable to indicate handler has not been called |
| 2. Set the signal handler for SIGQUIT to handler |
| 3. Call sigaction with a null act |
| 4. raise SIGQUIT |
| 5. Verify handler was called. |
