byteorder(3N)                                                 byteorder(3N)

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

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

     ulong htonl(ulong hostlong);

     ushort htons(ushort hostshort);

     ulong ntohl(ulong netlong);

     ushort ntohs(ushort netshort);

DESCRIPTION
     These routines convert 16 and 32 bit quantities between network byte
     order and host byte order. On some architectures these routines are
     defined as NULL macros in the include file <netinet/in.h>. On other
     architectures, if their host byte order is different from network byte
     order, these routines are functional.

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

SEE ALSO
     gethostent(3N), getservent(3N)
