| * Test that the sigwaitinfo() function shall select the pending signal |
| from the set set, and atomically clear it from the system's set of |
| pending signals. |
| |
| Steps: |
| 1. Register signal SIGTOTEST with the handler myhandler |
| 2. Block SIGTOTEST from the process |
| 3. Raise the signal, causing it to be pending |
| 4. Call sigwaitinfo() and verify that the signal is no longer pending. |
