\title Endian Conversion Functions
\ingroup architecture
\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.

/*!
\fn T qFromBigEndian(T src)

\relates <QtEndian>
\overload
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.
