signal Action Constants

#include <signal.h>

Remarks

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

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.
