PURPOSE

Converts values between host and Internet network byte order.

LIBRARY

Internet Library (libc.a)

SYNTAX

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




      unsigned long htonl (hostlong)        unsigned long ntohl (netlong)
      unsigned long hostlong;               unsigned long netlong;

      unsigned short htons (hostshort)      unsigned short ntohs (netshort)
      unsigned short hostshort;             unsigned short netshort;



DESCRIPTION

These subroutines convert 16- and 32-bit quantities between network byte order
and host byte order.  On machines already in network byte order (such as the
IBM System/370) these routines are defined as null macros in the include file
netinet/in.h.

These subroutines are often used in conjunction with Internet addresses and
ports as returned by the gethostent and getservent subroutines.
