DESCRIPTION
     The bswap16(), bswap32(), and 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 be16toh(), be32toh(), and 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 argu-
     ment on big endian systems.

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

     The htobe16(), htobe32(), and 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 htole16(), htole32(), and htole64() functions return an 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 be16enc(), be16dec(), be32enc(), be32dec(), be64enc(), be64dec(), le16enc(), le16dec(),
     le32enc(), le32dec(), le64enc(), and le64dec() functions encode and decode integers to/from
     octet stream on any alignment in big/little endian format.

HISTORY
     The hto*() and *toh() functions first appeared in NetBSD 1.5.  These were later ported to
     FreeBSD 5.0.  These functions were originally introduced to handle PCI bus master devices
     that (via DMA) transfer little endian data even on big endian systems.

     The encode/decode functions first appeared in FreeBSD 5.1.  These were later ported to
     NetBSD 3.0 as a part of the uuidgen(2) support.
