<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_817_83_2include_2fuse__lowlevel_8h.html#ab14032b74b0a57a2b3155dd6ba8d6095">fuse_lowlevel_notify_inval_entry()</a> and <a class="el" href="fuse-3_817_83_2include_2fuse__lowlevel_8h.html#a93afcd63bf5f93633637215c6c662a70">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_33s current_time
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

$ sleep 5; stat mnt/$file

</pre><p> To use the function <a class="el" href="fuse-3_817_83_2include_2fuse__lowlevel_8h.html#a93afcd63bf5f93633637215c6c662a70">fuse_lowlevel_notify_expire_entry()</a> instead of <a class="el" href="fuse-3_817_83_2include_2fuse__lowlevel_8h.html#ab14032b74b0a57a2b3155dd6ba8d6095">fuse_lowlevel_notify_inval_entry()</a>, use the command line option –only-expire</p>
<p>Another possible command-line option is –inc-epoch, which will use the FUSE low-level function <a class="el" href="include_2fuse__lowlevel_8h.html#aaea2c4ca0eae51e737350d81f731732a">fuse_lowlevel_notify_increment_epoch()</a> instead. This will function will force the invalidation of all dentries next time they are revalidated. Note that –inc-epoch and –only-expire options are mutually exclusive.</p>
