| This program tests the assertion that the lowest pending signal will be |
| selected by sigwaitinfo() if there are any multiple pending signals in the |
| range SIGRTMIN to SIGRTMAX. |
| |
| Steps: |
| - Register for myhandler to be called when any signal between SIGRTMIN |
| and SIGRTMAX is generated, and make sure SA_SIGINFO is set. |
| - Also, make sure that all of these signals are added to the set that |
| will be passed to sigwaitinfo(). |
| - Block all of these signals from the process. |
| - Raise all of these signals using sigqueue. |
| - call sigwaitinfo() and verify that it returns SIGRTMIN |
