Receive some data on the socket.
template<
typename MutableBufferSequence>
std::size_t receive(
const MutableBufferSequence & buffers,
socket_base::message_flags in_flags,
socket_base::message_flags & out_flags);
This function is used to receive data on the sequenced packet socket. The function call will block until data has been received successfully, or until an error occurs.
One or more buffers into which the data will be received.
Flags specifying how the receive call is to be made.
After the receive call completes, contains flags associated with
the received data. For example, if the socket_base::message_end_of_record
bit is set then the received data marks the end of a record.
The number of bytes received.
Thrown on failure. An error code of asio::error::eof
indicates that the connection was closed by the peer.
The receive operation may not receive all of the requested number of
bytes. Consider using the read
function if you need to ensure that the requested amount of data is read
before the blocking operation completes.
To receive into a single data buffer use the buffer
function as follows:
socket.receive(asio::buffer(data, size), 0, out_flags);
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.
