User-Added Signals

Notes on Handlers for User-Defined Signals

When you add new signals, the full array of signal-handling functions, including siginfo , sigprocmask , and sigsuspend , can be used in your program to control handling of the new signals. In some cases, you may want to define the new signal so that it does not permit the use of longjmp or return in a handler. Refer to Executive Routine for more information.
