ABORT(3)                      Linux Programmer's Manual                      ABORT(3)

NAME         top

       abort - cause abnormal process termination

SYNOPSIS         top

       #include <stdlib.h>

       void abort(void);

DESCRIPTION         top

       The abort() first unblocks the SIGABRT signal, and then raises that signal for
       the calling process.  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         top

       The abort() function never returns.
