DESCRIPTION

The Fn bswap16 , Fn bswap32 , and Fn bswap64 functions return a byte order swapped integer. On big endian systems, the number is converted to little endian byte order. On little endian systems, the number is converted to big endian byte order.

The Fn be16toh , Fn be32toh , and Fn be64toh functions return a big endian byte ordered integer converted to the system's native byte order. The return value will be the same as the argument on big endian systems.

The Fn le16toh , Fn le32toh , and Fn le64toh functions return a little endian byte ordered integer converted to the system's native byte order. The return value will be the same as the argument on little endian systems.

The Fn htobe16 , Fn htobe32 , and Fn htobe64 functions return an integer in the system's native byte order converted to big endian byte order. The return value will be the same as the argument on big endian systems.

The Fn htole16 , Fn htole32 , and Fn htole64 functions return a integer in the system's native byte order converted to little endian byte order. The return value will be the same as the argument on little endian systems.

The Fn be16enc , Fn be16dec , Fn be32enc , Fn be32dec , Fn be64enc , Fn be64dec , Fn le16enc , Fn le16dec , Fn le32enc , Fn le32dec , Fn le64enc , and Fn le64dec functions encode and decode integers to/from byte strings on any alignment in big/little endian format.

HISTORY

The Fn hto* and Fn *toh functions first appeared in Fx 5.0 , and were originally developed by the Nx project.

The encode/decode functions first appeared in Fx 5.1 .
