basic_datagram_socket::send (1 of 3 overloads)

Send some data on a connected socket.

template<
    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.

Parameters

buffers

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

Return Value

The number of bytes sent.

Exceptions

boost::system::system_error

Thrown on failure.

Remarks

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

Example

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.
