basic_seq_packet_socket::receive (3 of 3 overloads)

Receive some data on a connected socket.

template<
    typename MutableBufferSequence>
std::size_t receive(
    const MutableBufferSequence & buffers,
    socket_base::message_flags in_flags,
    socket_base::message_flags & out_flags,
    asio::error_code & ec);

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.

in_flags

Flags specifying how the receive call is to be made.

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.

ec

Set to indicate what error occurred, if any.

Return Value

The number of bytes received. Returns 0 if an error occurred.

Remarks

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.
