*dos.h - definitions for MS-DOS interface routines
|
|
*
|
|
* Copyright (c) 1985-2001, Microsoft Corporation. All rights reserved.
|
|
*
|
|
*Purpose:
|
|
* Defines the structs and unions used for the direct DOS interface
|
|
* routines; includes macros to access the segment and offset
|
|
* values of far pointers, so that they may be used by the routines; and
|
|
* provides function prototypes for direct DOS interface functions.
|
|
*
|
|
* [Public]
|
|
*
|
|
*Revision History:
|
|
* 06-11-87 JCR Added find_t
|
|
* 06-15-87 JCR Added O_NOINHERIT
|
|
* 06-18-87 JCR Added some DOS function prototypes
|
|
* 06-19-87 JCR Moved O_NOINHERIT to fcntl.h
|
|
* 06-25-87 JMB Added _HARDERR_* constants
|
|
* 06-25-87 SKS Added diskfree_t, dosdate_t, dostime_t structures
|
|
* 06-25-87 JCR Added _A_NORMAL, etc. constants
|
|
* 07-17-87 JCR Added _chain_intr, also the "interrupt" type to
|
|
* _dos_setvec and _dos_getvec.
|
|
* 07-27-87 SKS Added several _dos_*() functions, _disable()/_enable()
|
|
* 08-17-87 PHG Fixed bad prototype for _dos_getdiskfree()
|
|
* 10-08-87 JCR Added _CDECL to prototypes with "interrupt" declaration
|
|
* (needed for compiling with -Gc switch).
|
|
* 09-27-88 JCR 386 version
|
|

|
|
* 05-03-89 JCR Added _INTERNAL_IFSTRIP for relinc usage
|
|
* 07-25-89 GJF Major cleanup. Alignment of struct fields is now
|
|
* protected by pack pragmas. Now specific to 386.

|
|
* 11-02-89 JCR Changed "DLL" to "_DLL"
|
|

|
|
* stuff. Also, removed some (now) useless preprocessor
|
|
* directives.
|
|
* 03-22-90 GJF Replaced _cdecl with _CALLTYPE1 in prototype and with
|
|
* _VARTYPE1 in variable declaration.
|
|

|
|
* 01-23-91 GJF Removed segread() prototype.
|
|
* 04-04-91 GJF Added version info variables (_WIN32_).
|
|
* 08-20-91 JCR C++ and ANSI naming
|
|
* 08-26-91 BWM Added _peek, poke, and _getvideoaddr (_DOSX32_).
|
|
* 08-26-91 BWM Removed _harderr constants, replaced by _seterrormode.
|
|
* 08-26-91 BWM Removed datetime prototypes, replaced by systime functions.
|
|
* 09-05-91 JCR Added missing #endif (bug fix), removed obsolete stuff
|
|
* 09-16-91 BWM Fixed reversed #ifdef on screen address constants.
|
|
* 01-22-92 GJF Fixed up definitions of global variables for build of,
|
|
* and users of, crtdll.dll.
|
|
* 03-30-92 DJM POSIX support.
|
|
* 06-02-92 SKS Fix typo in DLL declaration of _osmajor
|
|
* Add declartion of _pgmptr
|
|
* 08-07-92 GJF Function calling type and variable type macros.
|
|
* 01-21-93 GJF Removed support for C6-386's _cdecl.
|
|
* 04-06-93 SKS Replace _CRTAPI1/2 with __cdecl, _CRTVAR1 with nothing
|
|
* Remove support for DOSX32, OS/2, etc.
|

* Remove obsolete vars and vars moved to STDLIB.H
|
|
* Remove duplicate references to _osver, etc.
|
|
* Remove obsolete functions peek, poke, etc.
|
|
* 04-07-93 SKS Add _CRTIMP keyword for CRT DLL model
|
|
* 06-15-93 GJF Restored prototypes for _enable, _disable.
|
|
* 09-01-93 GJF Merged Cuda and NT SDK versions.
|
|
* 11-19-93 CFW Add _wpgmptr.
|
|
* 11-03-94 GJF Ensure 8 byte alignment.
|
|
* 12-15-94 XY merged with mac header
|
|

|
|
* 02-14-95 CFW Clean up Mac merge.
|
|
