BYTEORDER(3) BSD Library Functions Manual BYTEORDER(3)NAMEhtonl, htons, ntohl, ntohs -- convert values between host and network byte orderLIBRARYStandard C Library (libc, -lc)SYNOPSIS#include <arpa/inet.h> or #include <netinet/in.h> uint32_t htonl(uint32_t hostlong); uint16_t htons(uint16_t hostshort); uint32_t ntohl(uint32_t netlong); uint16_t ntohs(uint16_t netshort);DESCRIPTIONThese 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).SEE ALSOgethostbyname(3), getservent(3), byteorder(9)STANDARDSThe byteorder functions conform to IEEE Std 1003.1-2001 (``POSIX.1'').HISTORYThe byteorder functions appeared in 4.2BSD.BUGSOn the VAX bytes are handled backwards from most everyone else in the world. This is not expected to be fixed in the near future.BSDMarch 20, 2005 BSD
