       #include <sys/types.h>

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

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

       hostlong = ntohl(netlong);

       u_short hostshort, netshort;

Description
       These routines convert 16-bit and  32-bit  quantities  between  network
       byte order and host byte order.	On some non-ULTRIX machines these rou‐
       tines are defined as null macros in the include file <netinet/in.h>.

       These routines are most often used with Internet addresses and ports as
       returned by and

Restrictions
