exit(3C)

NAME

     exit, _exithandle - terminate process

SYNOPSIS

     #include <stdlib.h>

     void exit(int status);

     void _exithandle(void);

DESCRIPTION

     The exit() function terminates a process  by  calling  first
     _exithandle() and then _exit() (see exit(2)).

     The  _exithandle() function calls any  functions  registered
     through  the  atexit(3C)  function  in  the reverse order of
     their  registration.  This  action  includes  executing  all
     finalization  code  from  the  .fini sections of all objects
     that are part of the process.

     The _exithandle() function is intended  for  use  only  with
     _exit(),  and  allows  for  specialized  processing  such as
     dldump(3DL) to be performed. Normal process execution should
     not be continued after a call to _exithandle() has occurred,
     as internal data structures may have been torn down  due  to
     atexit() or .fini processing.

     The symbols EXIT_SUCCESS and EXIT_FAILURE are defined in the
     header  <stdlib.h> and may be used as the value of status to
     indicate successful  or  unsuccessful  termination,  respec-
     tively.
