+FUNCTION
+<<_Exit>>---end program execution with no cleanup processing
+
+INDEX
+	_Exit
+
+ANSI_SYNOPSIS
+	#include <stdlib.h>
+	void _Exit(int <[code]>);
+
+TRAD_SYNOPSIS
+	#include <stdlib.h>
+	void _Exit(<[code]>)
+	int <[code]>;
+
+DESCRIPTION
+Use <<_Exit>> to return control from a program to the host operating
+environment.  Use the argument <[code]> to pass an exit status to the
+operating environment: two particular values, <<EXIT_SUCCESS>> and
+<<EXIT_FAILURE>>, are defined in `<<stdlib.h>>' to indicate success or
+failure in a portable fashion.
+
+<<_Exit>> differs from <<exit>> in that it does not run any
+application-defined cleanup functions registered with <<atexit>> and
+it does not clean up files and streams.  It is identical to <<_exit>>.
+
+RETURNS
+<<_Exit>> does not return to its caller.
+
+PORTABILITY
+<<_Exit>> is defined by the C99 standard.
+
+Supporting OS subroutines required: <<_exit>>.
