<name name="subsystem_spec" arity="1" since=""/>
<fsummary>Returns the subsystem specification that allows an SSH daemon to handle the subsystem "sftp".</fsummary>
<desc>
<p>Is to be used together with <c>ssh:daemon/[1,2,3]</c></p>
<p>The <c>Name</c> is <c>"sftp"</c> and
<c>CbMod</c> is the name of the Erlang module implementing the subsystem using the
<seealso marker="ssh_server_channel">ssh_server_channel</seealso> (replaces ssh_daemon_channel) behaviour.
</p>
<p>Options:</p>
<taglist>
<tag><c>cwd</c></tag>
<item>
<p>Sets the initial current working directory for the server.</p>
</item>
<tag><c>file_handler</c></tag>
<item>
<p>Determines which module to call for accessing
the file server. The default value is <c>ssh_sftpd_file</c>, which uses the
<seealso marker="kernel:file">file</seealso> and <seealso marker="stdlib:filelib">filelib</seealso>
APIs to access the standard OTP file server. This option can be used to plug in
other file servers.</p>
</item>
<tag><c>max_files</c></tag>
<item>
<p>The default value is <c>0</c>, which means that there is no upper limit.
If supplied, the number of filenames returned to the SFTP client per <c>READDIR</c>
request is limited to at most the given value.</p>
</item>
<tag><c>root</c></tag>
<item>
<p>Sets the SFTP root directory. Then the user cannot see any files
above this root. If, for example, the root directory is set to <c>/tmp</c>,
then the user sees this directory as <c>/</c>. If the user then writes
<c>cd /etc</c>, the user moves to <c>/tmp/etc</c>.
</p>
</item>
<tag><c>sftpd_vsn</c></tag>
<item>
<p>Sets the SFTP version to use. Defaults to 5. Version 6 is under
development and limited.</p>
