<h3 class="section">7.45 <code>.internal <var>names</var></code></h3>
<a name="index-internal-directive"></a>
<a name="index-visibility-1"></a>
<p>This is one of the ELF visibility directives. The other two are
<code>.hidden</code> (see <a href="Hidden.html#Hidden"><code>.hidden</code></a>) and
<code>.protected</code> (see <a href="Protected.html#Protected"><code>.protected</code></a>).
</p>
<p>This directive overrides the named symbols default visibility (which is set by
their binding: local, global or weak). The directive sets the visibility to
<code>internal</code> which means that the symbols are considered to be <code>hidden</code>
(i.e., not visible to other components), and that some extra, processor specific
processing must also be performed upon the symbols as well.
