| Test case for assertion #1 of the sigaction system call that shows |
| sigaction (when used with a non-null act pointer) changes the action |
| for a signal. |
| |
| Steps: |
| 1. Initialize a global variable to indicate the signal |
| handler has not been called. (A signal handler of the |
| prototype "void func(int signo);" will set the global |
| variable to indicate otherwise. |
| 2. Use sigaction to setup a signal handler for SIGTTIN |
| 3. Raise SIGTTIN. |
| 4. Verify the global indicates the signal was called. |
