Looks at the response status code and headers in msg
and determines if they contain a valid WebSocket handshake response (
given the handshake request in msg
's request headers).
If supported_extensions
is non-null, extensions included in the response
"Sec-WebSocket-Extensions" are verified too. Accepted extensions are returned in accepted_extensions
parameter if non-
null.
This is a low-level function; if you use [[email protected]_connect_async] to create a WebSocket connection, it will call this for you.
