WALK(5)                                                   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 response.

     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 evalu-
          ate file names: bind, create, mount, open, stat, wstat.
