| UDPTransmit (Family family=IPV4) |
| Create a UDP transmitter.
|
| UDPTransmit (const IPV4Address &bind, tpport_t port=5005) |
| Create a UDP transmitter, bind it to a specific interface and port address so that other UDP sockets on remote machines (or the same host) may find and send UDP messages to it, and associate it with a given port on a peer host.
|

|
SOCKET | getTransmitter (void) |
Error | setMulticast (bool enable) |

| Create a UDP socket bound by a service name.
|
| UDPSocket (const IPV4Address &bind, tpport_t port) |
| Create a UDP socket and bind it to a specific interface and port address so that other UDP sockets on remote machines (or the same host) may find and send UDP messages to it.

|
void | setPeer (const char *service) |
| Associate socket with a named connection.
|
void | connect (const char *service) |
Error | disconnect (void) |
| Disassociate this socket from any host connection.
|
virtual | ~Socket () |
| The socket base class may be "thrown" as a result of an error, and the "catcher" may then choose to destroy the object.
|
Socket & | operator= (const Socket &from) |
| Sockets may also be duplicated by the assignment operator.
|
virtual IPV4Host | getIPV4Sender (tpport_t *port=NULL) const |

|
Error | setKeepAlive (bool enable) |
| Set the keep-alive status of this socket and if keep-alive messages will be sent.
|

| Can test to see if this socket is "connected", and hence whether a "catch" can safely call getPeer().
|
bool | isActive (void) const |
| Test to see if the socket is at least operating or if it is mearly initialized.
|
bool | operator! () const |
| Operator based testing to see if a socket is currently active.
