However, these versions ALWAYS read from the console,* even when standard input is redirected.**Revision History:* 06-08-89 PHG Module created, based on asm version* 03-12-90 GJF Made calling type _CALLTYPE1, added #include* <cruntime.h> and fixed the copyright. Also, cleaned* up the formatting a bit.* 06-05-90 SBM Recoded as pure 32-bit, using new file handle state bits* 07-24-90 SBM Removed '32' from API names* 10-03-90 GJF New-style function declarators.* 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.* 01-25-91 SRW Get/SetConsoleMode parameters changed (_WIN32_)* 02-18-91 SRW Get/SetConsoleMode required read/write access (_WIN32_)* 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_].* 12-11-92 GJF Initialize character buffer to 0 (int ch = 0;) and* use ReadConsole instead of ReadFile.* 03-20-93 GJF Completely rewritten, Cruiser support purged, _kbhit* (also rewritten) and _ungetch also merged in.* 04-06-93 SKS Replace _CRTAPI* with __cdecl* Change GetExtendedKeyCode to _getextendedkeycode* 05-10-93 GJF Fixed bug in _kbhit, pointer passed to free no* longer pointed to the allocated block.* 01-28-94 CFW Let's also look at the RIGHT_CTRL_PRESSED.* 09-06-94 CFW Replace MTHREAD with _MT.* 12-03-94 SKS Clean up OS/2 references* 01-13-95 GJF getche() should not echo a pushback character.* 01-10-95 CFW Debug CRT allocs.* 06-23-95 GJF Use _alloca instead of malloc/free. Also, make we* really need the event buffer before allocating it.* 10-05-95 SKS Remove two // commented-out lines
* 12-08-95 SKS _coninph is now initialized on demand.* 02-07-98 GJF Changes for Win64: _coninph is now an intptr_t.* 12-10-99 GB Added support for recovery from stack overflow around* _alloca().* 04-25-00 GB exposed getextendedkeycode for use by _getwch()* 03-13-01 PML Fix heap leak if _alloca fails (vs7#224864)* 04-29-02 GB Added try-finally arounds lock-unlock.********************************************************************************/
