*cputs.c - direct console output
*
*       Copyright (c) 1989-2001, Microsoft Corporation. All rights reserved.
*
*Purpose:
*       defines _cputs() - write string directly to console
*
*Revision History:
*       06-09-89  PHG   Module created, based on asm version
*       03-12-90  GJF   Made calling type _CALLTYPE2 (for now), added #include
*                       <cruntime.h> and fixed the copyright. Also, cleaned up
*                       the formatting a bit.
*       04-10-90  GJF   Now _CALLTYPE1.
*       06-05-90  SBM   Recoded as pure 32-bit, using new file handle state bits
*       07-24-90  SBM   Removed '32' from API names
*       09-28-90  GJF   New-style function declarator.
*       12-04-90  SRW   Changed to include <oscalls.h> instead of <doscalls.h>
*       12-06-90  SRW   Added _CRUISER_ and _WIN32 conditionals.
*       01-16-91  GJF   ANSI naming.
*       02-19-91  SRW   Adapt to OpenFile/CreateFile changes (_WIN32_)
*       02-25-91  MHL   Adapt to ReadFile/WriteFile changes (_WIN32_)
*       07-26-91  GJF   Took out init. stuff and cleaned up the error
*                       handling [_WIN32_].
*       04-06-93  SKS   Replace _CRTAPI* with __cdecl
*       04-19-93  GJF   Use WriteConsole instead of WriteFile.
*       09-06-94  CFW   Remove Cruiser support.
*       12-08-95  SKS   _confh is now initialized on demand
*       02-07-98  GJF   Changes for Win64: _confh is now an intptr_t.
*       12-18-98  GJF   Changes for 64-bit size_t.
