BYTEORDER(3) BSD Library Functions Manual BYTEORDER(3)
htonl, htons, ntohl, ntohs -- convert values between host and network byte order
Standard C Library (libc, -lc)
These routines convert 16 and 32 bit quantities between network byte order and host byte
order. On machines which have a byte order which is the same as the network order, routines
are defined as null macros.
These routines are most often used in conjunction with Internet addresses and ports as
returned by gethostbyname(3) and getservent(3).
gethostbyname(3), getservent(3), byteorder(9)
The byteorder functions conform to IEEE Std 1003.1-2001 (``POSIX.1'').
The byteorder functions appeared in 4.2BSD.
On the VAX bytes are handled backwards from most everyone else in the world. This is not
expected to be fixed in the near future.
