byteorder(3N)                                       byteorder(3N)



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

SYNOPSIS
     #include <sys/types.h>
     #include <netinet/in.h>

     netlong = htonl(hostlong);
     ulong netlong, hostlong;

     netshort = htons(hostshort);
     ushort netshort, hostshort;

     hostlong = ntohl(netlong);
     ulong hostlong, netlong;

     hostshort = ntohs(netshort);
     ushort hostshort, netshort;

DESCRIPTION
     These routines convert 16 and 32 bit quantities between net-
     work byte order and host byte order.  On machines whose byte
     order matches network byte order, these routines are defined
     as null macros.

     These routines are most often used in conjunction with
     Internet addresses and ports as returned by
     gethostbyname(3N) and getservent(3N).
