C++ POCO库中文编程参考指南（7） Poco::Net::DatagramSocket2013-01-101 构造函数

创建一个未连接的 IPv4 数据报 Socket：

DatagramSocket（）;

创建一个指定 IP 类型（IPv4 或 IPv6）的数据报 Socket：

explicit DatagramSocket（IPAddress::Family family）;

创建一个指定 SocketAddress 的数据报 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 重载运算符

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 连接与绑定

void connect（const SocketAddress& address）;

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

3.2 收发数据且不考虑 client

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

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

3.3 手法数据且获取 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 收发广播

void setBroadcast （bool flag）;

bool getBroadcast（） const;

4 protected 函数

DatagramSocket（SocketImpl* pImpl）;
