- clunk fid-value reply! error!procedure
This corresponds to a 9P Tclunk request. The message consists purely of the fid, so it is not passed to the handler. fid-value is the value bound to the fid being clunked.
If the clunk succeeds, reply! should be called and passed an empty list.
If the clunk fails, error! should be called with a suitable error message.
The default implemention calls reply! with an empty list.
