basic_datagram_socket::send (1 of 3 overloads)

Send some data on a connected socket.

    typename ConstBufferSequence>
std::size_t send(
    const ConstBufferSequence & buffers);

This function is used to send data on the datagram socket. The function call will block until the data has been sent successfully or an error occurs.



One ore more data buffers to be sent on the socket.

Return Value

The number of bytes sent.



Thrown on failure.


The send operation can only be used with a connected socket. Use the send_to function to send data on an unconnected datagram socket.


To send a single data buffer use the buffer function as follows:

socket.send(boost::asio::buffer(data, size)); 

See the buffer documentation for information on sending multiple buffers in one go, and how to use it with arrays, boost::array or std::vector.
