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) ;

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.
