Functions to convert between little and big endian representations of numbers.
template<typename T >
| T qFromBigEndian |
( |
const uchar * |
source | ) |
|
|
inline |
Reads a big-endian number from memory location source 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 source.
There are no data alignment constraints for source.
- Note
- Template type T can either be a qint16, qint32 or qint64. Other types of integers such as qlong are not supported.

template<typename T >
| T qFromBigEndian |
( |
T |
source | ) |
|
|
inline |
Converts source 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 this will return source with the byte order swapped, otherwise it will return source.

template<typename T >
| T qFromLittleEndian |
( |

|

Converts source from little endian byte order and returns the number in host byte order representation of that number. On CPU architectures where the host byte order is big-endian this will return source with the byte order swapped, otherwise it will return source.
template<typename T >
| T qToBigEndian |
( |
T |
source | ) |
|
|
inline |
Converts source from host byte order and returns the number in big-endian byte order representation of that number. On CPU architectures where the host byte order is little-endian this will return source with the byte order swapped, otherwise it will return source.
template<typename T >
| void qToBigEndian |
( |
T |
source, |
|
|
uchar * |
dest |
|
) |
| |
|
inline |
Writes the number source with template type T to the memory location at dest in big-endian byte order. Template type T can only be an integer data type (signed or unsigned). There are no data alignment constraints for dest.
