BYTEORDER(3) DragonFly Library Functions Manual BYTEORDER(3)
htonl, htons, ntohl, ntohs -- convert values between host and network
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.
