Enclose #pragma-s * in #ifdef _MSC_VER * 04-12-94 SKS Add __cdecl keyword to dec/hex/oct functions and * operator >>. Add underscores to some parameter names. * 05-24-94 GJF Added definition of MAXLONGSIZ for internal use. * 06-06-94 CFW Fix ignore, bad return. * 08-12-94 GJF Disable warning 4514 instead of 4505. * 11-03-94 GJF Changed pack pragma to 8 byte alignment. * 01-26-95 CFW Removed QWIN ifdef. * 02-11-95 CFW Add _CRTBLD to avoid users getting wrong headers. * 02-14-95 CFW Clean up Mac merge. * 05-11-95 CFW Only for use by C++ programs. * 05-24-95 CFW Support for ignore(.., 0xFF). * 06-21-95 CFW Add inline support for ignore(.., 0xFF). * 07-07-95 CFW Fix ambiguous get. * 07-17-95 CFW Make get(char*,int,int) protected. * 12-14-95 JWM Add "#pragma once". * 04-09-96 SKS Change _CRTIMP to _CRTIMP1 for special iostream build * 04-15-96 JWM Remove _OLD_IOSTREAMS, add '#pragma comment(lib,"cirt")'. * 04-16-96 JWM '#include useoldio.h' replaces '#pragma comment(...)'. * 02-24-97 GJF Cleaned out obsolete support for _NTSDK. Also, * detab-ed. * 05-17-99 PML Remove all Macintosh support. * ****/ #if _MSC_VER > 1000 /*IFSTRIP=IGN*/ #pragma once #endif #ifdef __cplusplus #ifndef _INC_ISTREAM #define _INC_ISTREAM #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) #include #endif // _MSC_VER /* 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 */ #ifndef _INTERNAL_IFSTRIP_ /* Define _CRTIMP1 */ #ifndef _CRTIMP1 #ifdef CRTDLL1 #define _CRTIMP1 __declspec(dllexport) #else /* ndef CRTDLL1 */ #define _CRTIMP1 _CRTIMP #endif /* CRTDLL1 */ #endif /* _CRTIMP1 */ #endif /* _INTERNAL_IFSTRIP_ */ #include #ifdef _MSC_VER // C4069: "long double != double" #pragma warning(disable:4069) // disable C4069 warning // #pragma warning(default:4069) // use this to reenable, if desired // C4514: "unreferenced inline function has been removed" #pragma warning(disable:4514) // disable C4514 warning // #pragma warning(default:4514) // use this to reenable, if desired #endif // _MSC_VER #ifndef _INTERNAL_IFSTRIP_ #define MAXLONGSIZ 16 #endif /* _INTERNAL_IFSTRIP_ */ typedef long streamoff, streampos;
