Write a message to the stream.
template< class ConstBufferSequence> std::size_t write( ConstBufferSequence const& buffers);
This function is used to synchronously write a message to the stream. The call blocks until one of the following conditions is met:
This operation is implemented in terms of one or more calls to the next
The current setting of the
websocket::stream::binary option controls whether
the message opcode is set to text or binary. If the
websocket::stream::auto_fragment option is set,
the message will be split into one or more frames as necessary. The actual
payload contents sent may be transformed as per the WebSocket protocol
The buffers containing the entire message payload. The implementation will make copies of this object as needed, but ownership of the underlying memory is not transferred. The caller is responsible for ensuring that the memory locations pointed to by buffers remains valid until the completion handler is called.
The number of bytes written from the buffers. If an error occurred, this will be less than the sum of the buffer sizes.
Thrown on failure.
This function always sends an entire message. To send a message in fragments,
