120 058b0118 2005-01-03 devnull .B CFid*

125 058b0118 2005-01-03 devnull A new connection to a 9P server is typically established by
126 058b0118 2005-01-03 devnull .I fsmount
127 058b0118 2005-01-03 devnull or
128 058b0118 2005-01-03 devnull .IR nsmount .
129 058b0118 2005-01-03 devnull .I Fsmount
130 058b0118 2005-01-03 devnull initializes a new 9P conversation on the open file descriptor
131 058b0118 2005-01-03 devnull .IR fd ;
132 058b0118 2005-01-03 devnull .I nsmount
133 058b0118 2005-01-03 devnull connects to a service named
134 058b0118 2005-01-03 devnull .I name
135 058b0118 2005-01-03 devnull in the current name space directory
136 058b0118 2005-01-03 devnull (see

138 058b0118 2005-01-03 devnull Both attach to the root of the file system
139 058b0118 2005-01-03 devnull using the attach name
140 058b0118 2005-01-03 devnull .IR aname .

161 058b0118 2005-01-03 devnull corresponding to a 9P conversation on the file descriptor
162 d93fca6a 2005-02-11 devnull .I fd
163 d93fca6a 2005-02-11 devnull and then calls
164 d93fca6a 2005-02-11 devnull .IR fsversion
165 d93fca6a 2005-02-11 devnull to initialize the connection.
166 d93fca6a 2005-02-11 devnull .I Nsinit
167 d93fca6a 2005-02-11 devnull does the same for name space services.
168 058b0118 2005-01-03 devnull .I Fsversion
169 058b0118 2005-01-03 devnull executes a

173 058b0118 2005-01-03 devnull .I Fsauth
174 058b0118 2005-01-03 devnull executes an

176 058b0118 2005-01-03 devnull transaction, returning the new auth fid.

180 058b0118 2005-01-03 devnull can then be used to run the authentication protocol over the fid.)
181 058b0118 2005-01-03 devnull .I Fsattach
182 058b0118 2005-01-03 devnull executes an
183 058b0118 2005-01-03 devnull .IR attach (9p)
184 058b0118 2005-01-03 devnull transaction to connect to the root of a file tree served by the server.
185 058b0118 2005-01-03 devnull It presents

187 058b0118 2005-01-03 devnull (which may be nil)
188 058b0118 2005-01-03 devnull to establish identity.
189 058b0118 2005-01-03 devnull .I Fssetroot
190 058b0118 2005-01-03 devnull sets the root fid used by

198 058b0118 2005-01-03 devnull When a fid
199 058b0118 2005-01-03 devnull is no longer needed, it should be clunked by calling
200 058b0118 2005-01-03 devnull .I fsclose
201 058b0118 2005-01-03 devnull and then considered freed.
202 058b0118 2005-01-03 devnull Similarly, when the connection to the server is no longer needed,
203 058b0118 2005-01-03 devnull it should be closed by calling
204 058b0118 2005-01-03 devnull .IR fsunmount ,
205 058b0118 2005-01-03 devnull which will take care of calling
