| This program tests the assertion that the signal shall be ignored |
| if the value of the dist parameter is SIG_IGN. |
| |
| How this program tests this assertion is by setting up a handler |
| "myhandler" for SIGUSR1. Then another call to signal() is made about |
| SIGUSR1, this time with SIG_IGN as the value of the func parameter. |
| SIGUSR1 should be ignored now, so unless myhandler gets called when |
| SIGUSR1 is raised, the test passes, otherwise returns failure. |
