(* inet_aton() converts the Internet host address cp from the standard
numbers-and-dots notation into binary data and stores it in the structure
that inp points to. inet_aton returns nonzero if the address is
valid, zero if not.*)

(* The inet_addr() function converts the Internet host address cp from
numbers-and-dots notation into binary data in network byte order. If
the input is invalid, INADDR_NONE (usually -1) is returned. This is an
obsolete interface to inet_aton, described immediately above; it is
obsolete because -1 is a valid address (255.255.255.255), and inet_aton
provides a cleaner way to indicate error return. *)

(* The inet_network() function extracts the network number in host byte
order from the address cp in numbers-and-dots notation. If the input
is invalid, -1 is returned. *)

(* The inet_ntoa() function converts the Internet host address in given in
network byte order to a string in standard numbers-and-dots notation.
The string is returned in a statically allocated buffer, which subse-
quent calls will overwrite. *)

(* The inet_makeaddr() function makes an Internet host address in network
byte order by combining the network number net with the local address
host in network net, both in local host byte order. *)
