NAME

walk − descend a directory hierarchy

SYNOPSIS

Twalk tag[2] fid[2] name[28]
Rwalk tag[2] fid[2] qid[8]

DESCRIPTION

The walk request looks for the file name in the directory represented by fid.

For the walk to succeed, the file identified by fid must be a directory, and the implied user of the request must have permission to search the directory (see intro(5)).

After a successful walk, fid represents the specified file.  The qid for the new file is returned with the walk reply message. 

A walk of the name ..  in the root directory of a server is a no-op. 

ENTRY POINTS

The chdir system call causes a walk.  One or more walk messages may be generated by any of the following calls, which evaluate file names: bind, create, mount, open, remove, stat, unmount, wstat.  The file name element .  (dot) is interpreted locally and is not transmitted in walk messages.
