<div class="textblock"><p>This example implements a file system with a single file whose file name changes dynamically to reflect the current time.</p>
<p>It illustrates the use of the <a class="el" href="fuse-3_813_80_2include_2fuse__lowlevel_8h.html#ab14032b74b0a57a2b3155dd6ba8d6095">fuse_lowlevel_notify_inval_entry()</a> and <a class="el" href="fuse-3_813_80_2include_2fuse__lowlevel_8h.html#aae8edfd99383ba375981724470bb647f">fuse_lowlevel_notify_expire_entry()</a> functions.</p>
<p>To see the effect, first start the file system with the <code>--no-notify</code> </p><pre class="fragment">$ notify_inval_entry --update-interval=1 --timeout 30 --no-notify mnt/
</pre><p> Observe that <code>ls</code> always prints the correct directory contents (since <code>readdir</code> output is not cached):: </p><pre class="fragment">$ ls mnt; sleep 1; ls mnt; sleep 1; ls mnt

Time_is_15h_48m_34s  current_time
Time_is_15h_48m_35s  current_time
</pre><p> However, if you try to access a file by name the kernel will report that it still exists: </p><pre class="fragment">$ file=$(ls mnt/); echo $file
