abort – cause abnormal program termination

USAGE
       #include <stdlib.h>

       void abort(void);

DESCRIPTION
       The  abort()  function  causes  abnormal program termination unless the
       signal SIGABRT is caught and the signal handler does  not  return.   If
       the  abort()  function causes program termination, all open streams are
       closed and flushed.

       If the SIGABRT signal is blocked or ignored, the abort() function  will
       still override it.

RETURN VALUE
       The abort() function never returns.
