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 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 mes-
sages 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.
