| |
| * This sample test aims to check the following assertion: |
| * |
| * If Real-Time Signals extension is supported, and several signals in the |
| * range SIGRTMIN-SIGRTMAX are selected, the lower numbered is returned first. |
| |
| * The steps are: |
| * -> mask SIGRTMIN-SIGRTMAX |
| * -> raise the signals in the range SIGRTMIN-SIGRTMAX |
| * -> sigwait a signal and check we get always teh lowest-ordered. |
| |
| * The test fails if we select an unexpected signal. |
