Specifying Signal Actions

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 library also implements the more versatile sigaction facility. This section describes both facilities and gives suggestions on which to use when.

Basic Signal Handling The simple signal function.

Advanced Signal Handling The more powerful sigaction function.

Signal and Sigaction How those two functions interact.

Sigaction Function Example An example of using the sigaction function.

Flags for Sigaction Specifying options for signal handling.

Initial Signal Actions How programs inherit signal actions.
