C++ POCO庫中文編程參考指南（7） Poco::Net::DatagramSocket

1 建構函式

建立一個未串連的 IPv4 資料報 Socket：

DatagramSocket();

建立一個指定 IP 類型（IPv4 或 IPv6）的 資料報 Socket：

explicit DatagramSocket(IPAddress::Family family);

建立一個指定 SocketAddress 的資料報 Socket

DatagramSocket(const SocketAddress& address, bool reuseAddress = false);          DatagramSocket(const Socket& socket);       /// Creates the DatagramSocket with the SocketImpl       /// from another socket. The SocketImpl must be       /// a DatagramSocketImpl, otherwise an InvalidArgumentException       /// will be thrown.

2 重載運算子

DatagramSocket& operator = (const Socket& socket);       /// Assignment operator.       ///       /// Releases the socket's SocketImpl and       /// attaches the SocketImpl from the other socket and       /// increments the reference count of the SocketImpl.

3 常 用操作

3.1 串連與綁定

void connect(const SocketAddress& address);

void bind(const SocketAddress& address, bool reuseAddress = false);

3.2 收發資料且不考慮 client

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

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

3.3 手法 資料且擷取 client 的 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 收發廣播

void setBroadcast (bool flag);

bool getBroadcast() const;

4 protected 函數

DatagramSocket(SocketImpl* pImpl);
