NAME

       htons - Converts an unsigned short (16-bit) integer from host byte order to network byte order

LIBRARY

       Standard C Library (libc.so, libc.a)

SYNOPSIS

       #include <arpa/inet.h> in_port_t htons (      in_port_t hostshort) ;

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       htons():  XNS4.0

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

PARAMETERS

       Specifies a 16-bit integer in host byte order.

DESCRIPTION

       The  htons()  (host-to-network  short)  function  converts an unsigned short (16-bit) integer from host byte order to Internet network-byte
       order.

       The Internet network requires address and port reference data in network-byte order.  Use the htons() function to convert address and  port
       short integers from host byte order to Internet network-byte order.

RETURN VALUES

       Upon successful completion, the htons() function returns a 16-bit short integer in Internet network-byte order.

ERRORS

       Current industry standards do not define error values for the htons() function.

NAME

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

SYNOPSIS

       #include <arpa/inet.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 i386 the host byte order is Least Significant Byte first, whereas the network byte order, as used on the Internet, is Most Signifi-
       cant Byte first.

CONFORMING TO

       POSIX.1-2001.

       Some systems require the inclusion of <netinet/in.h> instead of <arpa/inet.h>.
