# SIGINT Macro

Interrupt signal.

Attention: This macro is not implemented by MPLAB XC8.

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.”
