/***
*cputs.c - direct console output
*
* Copyright (c) 1989-1993, 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_].
* 04-19-93 GJF Use WriteConsole instead of WriteFile.
