Read a complete message.
template< class DynamicBuffer> std::size_t read( DynamicBuffer& buffer, error_code& ec);
This function is used to read a complete message.
The call blocks until one of the following is true:
error::closed.
The algorithm, known as a composed operation, is
implemented in terms of calls to the next layer's read_some
and write_some functions.
Received message data is appended to the buffer. The functions got_binary and got_text may be used to query
the stream and determine the type of the last received message.
Until the call returns, the implementation will read incoming control frames and handle them automatically as follows:
control_callback will be
invoked for each control frame.
error::closed will be indicated.
The number of message payload bytes appended to the buffer.
