byteorder(3SOCKET)	   Sockets Library Functions	    byteorder(3SOCKET)

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

SYNOPSIS
       cc [ flag... ] file... -lsocket -lnsl [ library... ]
       #include <sys/types.h>
       #include <netinet/in.h>
       #include <inttypes.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
       These routines convert 16-bit 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,  the routines are functional when the host byte order is
       different from network byte order.

       The routines are most often used in conjunction with Internet addresses
       and  ports as returned by gethostent() and getservent(). See gethostby‐
       name(3NSL) and getservbyname(3SOCKET).
