<div><p>AF_INET address family sockets can be either connection-oriented
|
||
|
|
(type SOCK_STREAM) or they can be connectionless (type SOCK_DGRAM).</p>
|
||
|
|
<div class="section"><p>Connection-oriented AF_INET sockets use TCP as
|
||
|
|
the transport protocol. Connectionless AF_INET sockets use User Datagram Protocol
|
||
|
|
(UDP) as the transport protocol. When you create an AF_INET domain socket,
|
||
|
|
you specify AF_INET for the address family in the socket program. AF_INET
|
||
|
|
sockets can also use a type of SOCK_RAW. If this type is set, the application
|
||
|
|
connects directly to the IP layer and does not use either the TCP or UDP transports.</p>
