6.13.7 SIGSEGV Macro

Signals invalid access to storage.

Include

<signal.h>

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

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(SIGSEGV);
  printf("Program never reaches here.");
}

Example Output

SEGV

where SEGV stands for “invalid storage access.”
