Send a datagram to the specified endpoint.
template< typename ConstBufferSequence> std::size_t send_to( const ConstBufferSequence & buffers, const endpoint_type & destination);
This function is used to send a datagram to the specified remote endpoint. The function call will block until the data has been sent successfully or an error occurs.
One or more data buffers to be sent to the remote endpoint.
The remote endpoint to which the data will be sent.
The number of bytes sent.
Thrown on failure.
To send a single data buffer use the buffer
function as follows:
asio::ip::udp::endpoint destination( asio::ip::address::from_string("1.2.3.4"), 12345); socket.send_to(asio::buffer(data, size), destination);
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.
