| * Test that the raise(<signal>) function shall send the signal |
| * to the executing process when the executing process is a child |
| * process. |
| * 1) Set up a signal handler for a signal in the parent process. |
| * This handler returns failure if called. |
| * 2) Fork a child process. |
| * 2) In the child process: |
| * 3) Set up a signal handler for the same signal as in the parent process. |
| * This handler returns success if called. |
| * 4) Raise the signal. |
| * 5) If signal handler was called, return 1 (so WEXITSTATUS can test |
| * for success). |
| * 6) In parent, if 1 was received, test passed. |
| * This test is only performed on one signal. All other signals are |
| * considered to be in the same equivalence class. |
