WALK(5) 							File Formats Manual							   WALK(5)

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
       A call to chdir(2) causes a walk.  One or more walk messages may be generated by any of the following calls,  which  evaluate  file  names:
       bind,  create, exec, mount, open, remove, stat, unmount, wstat.	The file name element .  (dot) is interpreted locally and is not transmit-
       ted in walk messages.
