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

SYNOPSIS
       #include <netinet/in.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
       The htonl() function converts the unsigned integer hostlong from	 host
       byte order to network byte order.

       The  htons()  function  converts	 the unsigned short integer hostshort
       from host byte order to network byte order.

       The ntohl() function converts the unsigned integer netlong  from	 net-
       work byte order to host byte order.

       The ntohs() function converts the unsigned short integer netshort from
       network byte order to host byte order.

       On the i80x86 the host byte order is  Least  Significant	 Byte  first,
       whereas	the network byte order, as used on the Internet, is Most Sig-
       nificant Byte first.
