奇趣公司比较新的qt/emd版本

    Windows operating system. On Windows, the
    QSysInfo::WindowsVersion variable gives the version of the system
    on which the application is run.

    MS-DOS-based versions:

    \value WV_32s   Windows 3.1 with Win 32s
    \value WV_95    Windows 95
    \value WV_98    Windows 98
    \value WV_Me    Windows Me

    NT-based versions:

    \value WV_NT    Windows NT
    \value WV_2000  Windows 2000
    \value WV_XP    Windows XP
    \value WV_2003  Windows Server 2003
    \value WV_VISTA Windows Vista

    CE-based versions:

    \value WV_CE    Windows CE
    \value WV_CENET Windows CE .NET

    The following masks can be used for testing whether a Windows
    version is MS-DOS-based, NT-based, or CE-based:

    \value WV_DOS_based MS-DOS-based version of Windows
    \value WV_NT_based  NT-based version of Windows
    \value WV_CE_based  CE-based version of Windows

    \fn T qFromBigEndian(const uchar *src)

    Reads a big-endian number from memory location \a src and returns the number in the
    host byte order representation.
    On CPU architectures where the host byte order is little-endian (such as x86) this
    will swap the byte order; otherwise it will just read from \a src.

    Note that template type \c{T} can only be an integer data type (signed or unsigned).

    There are no data alignment constraints for \a src.
