C + + Poco library Chinese Programming Reference Guide (7) poco::net::D atagramsocket

1 constructors

Create a disconnected IPv4 datagram Socket:

Datagramsocket ();

Creates a datagram Socket that specifies the IP type (IPV4 or IPV6):

Explicit Datagramsocket (ipaddress::family Family);

Create a datagram Socket with a specified socketaddress

Datagramsocket (const socketaddress& address, bool 

reuseaddress = false);   
       
Datagramsocket (const socket& Socket);   
    Creates the Datagramsocket with the SocketImpl   
    ///from another socket. The SocketImpl must   
    is///a datagramsocketimpl, otherwise an invalidargumentexception   
    ///would be thrown.

2 Overloaded operators

datagramsocket& operator = (const socket& Socket);   
    Assignment operator.   
    ///releases the socket ' s SocketImpl and///attaches the SocketImpl from the other   
    socket and   
    /// Ements the reference count of the SocketImpl.

3 Common operations

3.1 Connections and bindings

void Connect (const socketaddress& address);

void bind (const socketaddress& address, BOOL reuseaddress = false);

3.2 Send and receive data without regard to client

int sendbytes (const void* buffer, int length, int flags = 0);

int receivebytes (void* buffer, int length, int flags = 0);

3.3 Manipulation data and obtaining client's socketaddress

int SendTo (const void* buffer, int length, const socketaddress& address, int flags = 0);

int ReceiveFrom (void* buffer, int length, socketaddress& address, int flags = 0);

3.4 Radio and transceiver

void Setbroadcast (bool flag);

BOOL Getbroadcast () const;

4 protected function

Datagramsocket (socketimpl* Pimpl);
