basic_raw_socket::send_to (1 of 3 overloads)

Send raw data 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 raw data to the specified remote endpoint. The function call will block until the data has been sent successfully or an error occurs.

Parameters

buffers: One or more data buffers to be sent to the remote endpoint.
destination: The remote endpoint to which the data will be sent.

Return Value

The number of bytes sent.

Exceptions

asio::system_error: Thrown on failure.

Example

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.
