NAME

       htonl - Converts an unsigned 32-bit integer from host byte order to Internet network-byte order

LIBRARY

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

SYNOPSIS

       #include <arpa/inet.h> in_addr_t htonl (      in_addr_t hostint) ;

STANDARDS

       htonl():  XNS4.0

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

PARAMETERS

       Specifies a 32-bit integer in host byte order.

DESCRIPTION

       The htonl() (host-to-network long) function converts an unsigned 32-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 htonl() function to convert address and port
       integers from Internet host byte order to Internet network-byte ordered integers.

RETURN VALUES

       Upon successful completion, the htonl() function returns a 32-bit integer in Internet network-byte order.

ERRORS

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