signal Action Constants
Visual Studio 2005
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.
