| <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This module is obsolete.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> |

| <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> |

| |
| <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. |
