| Test case for assertion #2 of the sigaction system call that shows |
| sigaction (when used with a non-null oact pointer) changes the action |
| for a signal. |
| |
| Steps: |
| 1. Call sigaction to set handler for SIGHUP to use handler1 |
| 2. Call sigaction again to set handler for SIGHUP to use handler2, |
| but this time use a non-null oarg and verify the sa_handler for |
| oarg is set for handler1. |
