     order

SYNOPSIS    [Toc]    [Back]

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

     u_long htonl(u_long hostlong);

     u_short htons(u_short hostshort);

     u_long ntohl(u_long netlong);

     u_short ntohs(u_short netshort);

DESCRIPTION    [Toc]    [Back]

     These routines convert 16 and 32 bit quantities between network byte
     order and host byte order.	 On machines such as the IRIS-4D series, these
     routines are defined as null macros in the	include	file <netinet/in.h>.

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