basic_seq_packet_socket::receive (1 of 3 overloads)

Receive some data on the socket.

template<
    typename MutableBufferSequence>
std::size_t receive(
    const MutableBufferSequence & buffers,
    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.

Parameters

buffers

One or more buffers into which the data will be received.

out_flags

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.

Return Value

The number of bytes received.

Exceptions

asio::system_error

Thrown on failure. An error code of asio::error::eof indicates that the connection was closed by the peer.

Example

To receive into a single data buffer use the buffer function as follows:

socket.receive(asio::buffer(data, size), 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.
