Next: Defining Handlers, Previous: Standard Signals, Up: Signal Handling [Contents][Index]
The simplest way to change the action for a signal is to use the
signal function. You can specify a built-in action (such as to
ignore the signal), or you can establish a handler.
The GNU C Library also implements the more versatile sigaction
facility. This section describes both facilities and gives suggestions
on which to use when.
