clunk – forget about a fid


size[4] Tclunk tag[2] fid[4]
size[4] Rclunk tag[2]


The clunk request informs the file server that the current file represented by fid is no longer needed by the client. The actual file is not removed on the server unless the fid had been opened with ORCLOSE.

Once a fid has been clunked, the same fid can be reused in a new walk or attach request.

Even if the clunk returns an error, the fid is no longer valid.


A clunk message is generated by close and indirectly by other actions such as failed open calls.
