285  * The standard Posix interface for signal handlers is not as useful
287  * (the signal number). For example:
295  *    signal(SIGINT, &my_signal_handler);
297  * The sigaction() function allows finer grained control of the signal
316  * The two additional arguments available to the signal handler are extensions
323  * The 3 arguments that Haiku provides to signal handlers are as follows:
324  * 1) The first argument is the (usual) signal number.
331  *    the time the signal was delivered to your thread. You can change the
332  *    fields of the structure. After your signal handler completes, the OS uses
344  * signal handlers get this as the last argument
