EXIT(3P)                   POSIX Programmer's Manual                  EXIT(3P)
PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the  corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.
NAME
       exit -- terminate a process
SYNOPSIS
       #include <stdlib.h>
       void exit(int status);
DESCRIPTION
       The functionality described on this reference page is aligned with  the
       ISO C  standard.  Any  conflict between the requirements described here
       and the ISO C standard is unintentional. This  volume  of  POSIX.1-2008
       defers to the ISO C standard.
       The  value of status may be 0, EXIT_SUCCESS, EXIT_FAILURE, or any other
       value, though only the least significant 8  bits  (that  is,  status  &
       0377) shall be available to a waiting parent process.
       The  exit()  function  shall  first  call  all  functions registered by
       atexit(), in the reverse order of their  registration,  except  that  a
       function  is  called after any previously registered functions that had
       already been called at the time it was  registered.  Each  function  is
       called  as  many times as it was registered. If, during the call to any
       such function, a call to the longjmp() function is made that would ter-
       minate the call to the registered function, the behavior is undefined.
       If  a  function  registered  by a call to atexit() fails to return, the
       remaining registered functions shall not be called and the rest of  the
       exit() processing shall not be completed. If exit() is called more than
       once, the behavior is undefined.
       The exit() function shall then flush all open  streams  with  unwritten
       buffered data and close all open streams. Finally, the process shall be
       terminated with the same consequences as described in  Consequences  of
       Process Termination.
RETURN VALUE
       The exit() function does not return.
