The action taken when the interrupt signal is received depends on the value of func.
Syntax
#include <signal.h>
Remarks
The func argument must be either a function address or one of the manifest constants listed below and defined in SIGNAL.H.
| Constant | Description |
|---|---|
SIG_DFL |
Uses system-default response. If the calling program uses stream I/O, buffers created by the run-time library aren't 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_GET |
Returns the current value of the signal. |
SIG_SGE |
Indicates an error occurred in the signal. |
SIG_ACK |
Indicates an acknowledgment was received. |
SIG_ERR |
A return type from a signal indicating an error has occurred. |
