<h1 align="CENTER">Module mod_dld</h1>
<strong><font color="red">This module is obsolete. As of
version 1.3 of Apache, it has been replaced with <a
href="mod_so.html">mod_so</a>.</font></strong> This module is
contained in the <code>mod_dld.c</code> file, and is not
compiled in by default. It provides for loading of executable
code and modules into the server at start-up time, using the
GNU dld library.
<h2>Summary</h2>
The optional dld module is a proof-of-concept piece of code
which loads other modules into the server as it is configuring
itself (the first time only; for now, rereading the config
files cannot affect the state of loaded modules), using the GNU
dynamic linking library, DLD. It isn't compiled into the server
by default, since not everyone has DLD, but it works when I try
it. (Famous last words.)
<p>Note that for some reason, <code>LoadFile /lib/libc.a</code>
seems to be required for just about everything.</p>
<p>Note: that DLD needs to read the symbol table out of the
server binary when starting up; these commands will fail if the
server can't find its own binary when it starts up, or if that
binary is stripped.</p>
<h2>Directives</h2>
<ul>

<h2><a id="loadfile" name="loadfile">LoadFile</a></h2>

<p>The LoadFile directive links in the named object files or
libraries when the server is started; this is used to load
additional code which may be required for some module to work.
<em>Filename</em> is relative to <a
href="core.html#serverroot">ServerRoot</a>.</p>

<h2><a id="loadmodule" name="loadmodule">LoadModule</a></h2>
<a href="directive-dict.html#Syntax"

<p>The LoadModule directive links in the object file or library
<em>filename</em> and adds the module structure named
<em>module</em> to the list of active modules. <em>Module</em>
is the name of the external variable of type
<code>module</code> in the file. Example:</p>
<blockquote>
<code>LoadModule ai_backcompat_module
modules/mod_ai_backcompat.o<br />
LoadFile /lib/libc.a</code>
</blockquote>
loads the module in the modules subdirectory of the ServerRoot.
