/*** *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 * 10-03-88 GJF Use M_I386, not I386 * 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. * 10-30-89 GJF Fixed copyright * 11-02-89 JCR Changed "DLL" to "_DLL" * 02-28-90 GJF Added #ifndef _INC_DOS and #include * stuff. Also, removed some (now) useless preprocessor * directives. * 03-22-90 GJF Replaced _cdecl with _CALLTYPE1 in prototype and with * _VARTYPE1 in variable declaration. * 12-28-90 SRW Added _CRUISER_ conditional around pack pragmas * 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 * 02-11-95 CFW Add _CRTBLD to avoid users getting wrong headers. * 02-14-95 CFW Clean up Mac merge. * 12-14-95 JWM Add "#pragma once". * 01-23-97 GJF Cleaned out obsolete support for _NTSDK and _CRTAPI*. * Also, detab-ed. * 09-30-97 JWM Restored not-so-obsolete _CRTAPI1 support. * 10-07-97 RDL Added IA64. * 05-13-99 PML Remove _CRTAPI1 * 05-17-99 PML Remove all Macintosh support. * ****/ #if _MSC_VER > 1000 /*IFSTRIP=IGN*/ #pragma once #endif #ifndef _INC_DOS #define _INC_DOS #if !defined(_WIN32) #error ERROR: Only Win32 target supported! #endif #ifndef _CRTBLD /* This version of the header files is NOT for user programs. * It is intended for use when building the C runtimes ONLY. * The version intended for public use will not have this message. */ #error ERROR: Use of C runtime library internal header file. #endif /* _CRTBLD */ #ifdef _MSC_VER /* * Currently, all MS C compilers for Win32 platforms default to 8 byte * alignment. */ #pragma pack(push,8) #endif /* _MSC_VER */ #ifdef __cplusplus extern "C" { #endif #ifndef _INTERNAL_IFSTRIP_ #include #endif /* _INTERNAL_IFSTRIP_ */ /* Define _CRTIMP */ #ifndef _CRTIMP #ifdef CRTDLL #define _CRTIMP __declspec(dllexport) #else /* ndef CRTDLL */ #ifdef _DLL #define _CRTIMP __declspec(dllimport) #else /* ndef _DLL */ #define _CRTIMP #endif /* _DLL */ #endif /* CRTDLL */ #endif /* _CRTIMP */ /* Define __cdecl for non-Microsoft compilers */ #if ( !defined(_MSC_VER) && !defined(__cdecl) ) #define __cdecl #endif #ifndef _WCHAR_T_DEFINED typedef unsigned short wchar_t; #define _WCHAR_T_DEFINED #endif #ifndef _DISKFREE_T_DEFINED /* _getdiskfree structure (duplicated in DIRECT.H) */ struct _diskfree_t { unsigned total_clusters; unsigned avail_clusters; unsigned sectors_per_cluster; unsigned bytes_per_sector; }; #define _DISKFREE_T_DEFINED #endif /* File attribute constants */ #define _A_NORMAL 0x00 /* Normal file - No read/write restrictions */ #define _A_RDONLY 0x01 /* Read only file */ #define _A_HIDDEN 0x02 /* Hidden file */ #define _A_SYSTEM 0x04 /* System file */ #define _A_SUBDIR 0x10 /* Subdirectory */ #define _A_ARCH 0x20 /* Archive file */ /* Function prototypes */ _CRTIMP unsigned __cdecl _getdiskfree(unsigned, struct _diskfree_t *); #ifdef _M_IX86 void __cdecl _disable(void); void __cdecl _enable(void); #endif /* _M_IX86 */ #if !__STDC__ /* Non-ANSI name for compatibility */ #define diskfree_t _diskfree_t #endif /* __STDC__ */ #ifdef __cplusplus } #endif #ifdef _MSC_VER #pragma pack(pop) #endif /* _MSC_VER */ #endif /* _INC_DOS */
