   2 FUNCTION
   3 <<_Exit>>---end program execution with no cleanup processing
   4
   5 INDEX
   6         _Exit

   8 SYNOPSIS
   9         #include <stdlib.h>
  10         void _Exit(int <[code]>);
  11
  12 DESCRIPTION
  13 Use <<_Exit>> to return control from a program to the host operating
  14 environment.  Use the argument <[code]> to pass an exit status to the
  15 operating environment: two particular values, <<EXIT_SUCCESS>> and
  16 <<EXIT_FAILURE>>, are defined in `<<stdlib.h>>' to indicate success or
  17 failure in a portable fashion.
  18
  19 <<_Exit>> differs from <<exit>> in that it does not run any
  20 application-defined cleanup functions registered with <<atexit>> and
  21 it does not clean up files and streams.  It is identical to <<_exit>>.
  22
  23 RETURNS
  24 <<_Exit>> does not return to its caller.
  25
  26 PORTABILITY
  27 <<_Exit>> is defined by the C99 standard.
  28
  29 Supporting OS subroutines required: <<_exit>>.
