| This program tests the assertion that the function shall be executed |
| when the signal occurs if the disp parameter is the address of a function. |
| |
| How this program tests this assertion is by setting up a handler |
| "myhandler" for SIGCHLD, and then raising that signal. If the |
| handler_called variable is anything but 1, then fail, otherwise pass. |
