BYTEORDER(3)               Linux Programmer's Manual              BYTEORDER(3)

NAME
       htonl,  htons,  ntohl,  ntohs - convert values between host and network
       byte order

SYNOPSIS
       #include <arpa/inet.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);

DESCRIPTION
       The htonl() function converts the unsigned integer hostlong  from  host
       byte order to network byte order.

       The htons() function converts the unsigned short integer hostshort from
       host byte order to network byte order.

       The ntohl() function converts the unsigned integer netlong from network
       byte order to host byte order.

       The  ntohs() function converts the unsigned short integer netshort from
       network byte order to host byte order.

       On the i386 the host  byte  order  is  Least  Significant  Byte  first,
       whereas  the  network byte order, as used on the Internet, is Most Sig-
       nificant Byte first.

CONFORMING TO
       POSIX.1-2001.

       Some  systems  require  the  inclusion  of  <netinet/in.h>  instead  of
       <arpa/inet.h>.
