BYTEORDER(3)               Linux Programmer’s Manual              BYTEORDER(3)



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 network 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 net-
       work byte order, as used on the Internet, is Most Significant Byte first.
