    \title Endian Conversion Functions

    \ingroup funclists

    \brief The <QtEndian> header provides functions to convert between

    little and big endian representations of numbers.

*/

/*!

    \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.
