Receive a datagram with the endpoint of the sender.
template< typename MutableBufferSequence> std::size_t receive_from( const MutableBufferSequence & buffers, endpoint_type & sender_endpoint);
This function is used to receive a datagram. The function call will block until data has been received successfully or an error occurs.
One or more buffers into which the data will be received.
An endpoint object that receives the endpoint of the remote sender of the datagram.
The number of bytes received.
Thrown on failure.
To receive into a single data buffer use the buffer
function as follows:
boost::asio::ip::udp::endpoint sender_endpoint; socket.receive_from( boost::asio::buffer(data, size), sender_endpoint);
See the buffer
documentation for information on receiving into multiple buffers in one
go, and how to use it with arrays, boost::array or std::vector.
