signal Action Constants

signal Action Constants

The action taken when the interrupt signal is received depends on the value of func.

#include <signal.h>

The func argument must be either a function address or one of the manifest constants listed below and defined in SIGNAL.H.

SIG_DFL

Uses system-default response. If the calling program uses stream I/O, buffers created by the run-time library are not flushed.

SIG_IGN

Ignores interrupt signal. This value should never be given for SIGFPE, since the floating-point state of the process is left undefined.

SIG_SGE

Indicates an error occurred in the signal.

SIG_ACK

Indicates an acknowledgement was received.

SIG_ERR

A return type from a signal indicating an error has occurred.
