SIGSEGV Macro

Signals invalid access to storage.

Include

<signal.h>

Prototype

#define SIGSEGV

Remarks

SIGSEGV is used as an argument for raise and/or signal. When used, the default behavior is to print an invalid storage request 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

#include <signal.h> /* for raise, SIGSEGV */
#include <stdio.h> /* for printf */

int main(void)
{
  raise(SIGSEGV);
  printf("Program never reaches here.");
}

Example Output

SEGV

where SEGV stands for “invalid storage access.”
