6.13.6 SIGINT Macro
Interrupt signal.
Include
<signal.h>
Remarks
SIGINT
is used as an argument for raise
and/or signal
. When used, the default behavior is to print an
interruption message and terminate the calling program. This may be overridden by a user
function that defines the signal handler actions. See signal
for an
example of a user-defined function.
Example
See the notes at the beginning of this chapter or section for
information on using printf()
or scanf()
(and other functions reading and writing the stdin
or
stdout
streams) in the example code.
#include <signal.h>
#include <stdio.h>
int main(void)
{
raise(SIGINT);
printf("Program never reaches here.");
}
Example Output
INT
where INT
stands for “interruption.”
