NAME

       abort - cause abnormal process termination

SYNOPSIS

       #include <stdlib.h>

       void abort(void);

DESCRIPTION

       The  abort()  first  unblocks the SIGABRT signal, and then raises that signal for the calling process (as
       though raise(3) was called).  This results in the abnormal termination of the process unless the  SIGABRT
       signal is caught and the signal handler does not return (see longjmp(3)).

       If the abort() function causes process termination, all open streams are closed and flushed.

       If  the  SIGABRT  signal is ignored, or caught by a handler that returns, the abort() function will still
       terminate the process.  It does this by restoring the default disposition for SIGABRT  and  then  raising
       the signal for a second time.

RETURN VALUE

       The abort() function never returns.
