<a name="id-1.7.7.5"></a><h2>Description</h2>
<p>
<span class="command"><strong>gtk-update-icon-cache</strong></span> creates mmapable cache
files for icon themes.
</p>
<p>
It expects to be given the <em class="replaceable"><code>PATH</code></em> to a icon theme
directory containing an <code class="filename">index.theme</code>, e.g.
<code class="filename">/usr/share/icons/hicolor</code>, and writes a
<code class="filename">icon-theme.cache</code> containing cached information about
the icons in the directory tree below the given directory.
</p>
<p>
GTK+ can use the cache files created by <span class="command"><strong>gtk-update-icon-cache</strong></span>
to avoid a lot of system call and disk seek overhead when the application
starts. Since the format of the cache files allows them to be mmaped
shared between multiple applications, the overall memory consumption is
reduced as well.
