_defs.h

希望我上传的这些东西可以对搞编程的程序员有点小小的帮助！谢谢！

/*  _defs.h

    Common definitions for pointer size and calling conventions.

    Calling conventions:
    _RTLENTRY       Specifies the calling convention used by the RTL

    _USERENTRY      Specifies the calling convention the RTL expects user
                    compiled functions to use (for callbacks)

    Export (and size for DOS) information:
    _EXPCLASS       Exports class if building DLL version of library
                    For DOS16 also provides size information

    _EXPDATA        Exports data if building DLL version of library

    _EXPFUNC        Exports function if building DLL version of library
                    For DOS16 also provides size information

    _FAR            Promotes data pointers to far in DLLs (DOS16 only)

    Obsolete versions:
    _Cdecl          Use _RTLENTRY
    _CLASSTYPE      Use _EXPCLASS
    _FARFUNC        Use _EXPFUNC
    _FARCALL        Use _EXPFUNC and declare function explicity __far
