    \fn T qFromBigEndian(const uchar *src)
    \since 4.3
    \relates <QtEndian>

    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 Template type \c{T} can either be a qint16, qint32 or qint64. Other types of
    integers, e.g., qlong, are not applicable.

    There are no data alignment constraints for \a src.

    Converts \a src from big-endian byte order and returns the number in host byte order
    representation of that number.
    On CPU architectures where the host byte order is little-endian (such as x86) this
    will return \a src with the byte order swapped; otherwise it will return \a src
    unmodified.

    in big-endian byte order.

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