* mod_dll.c - DLL module loader for Windows
* by Alexei Kosut, based on mod_dld.c by rst
*
* This module loads another module into the server that has been
* compiled as a DLL. It doesn't work perfectly, but well enough.
*
* To use, compile the module into a DLL. Then add the following to the
* server's config file (before any directives belonging to the loaded module):
*
* LoadModule module_name mod_name.dll
*
* module_name should be the name of the module (e.g. includes_module),
* and mod_name.dll should be the name of the DLL, relative to the server
* root.
*
* There is also a directive that will load a non-module DLL, if you'd
* like to load additional libraries into the server:
*
* LoadFile filename.dll
*
* Compiling a module as a DLL (using Microsoft Visual C++):
*
* 1. Add the following to the module source file's module record
* definition: MODULE_VAR_EXPORT. i.e. if you have
* "module foo_module;", replace it with
* "module MODULE+VAR_EXPORT foo_module;". If your module is to be
* compiled with both Windows and Unix, you may wish to use an #ifdef
* WIN32
*
* Note that your module should still work just fine compiled-in
* with this code bit there. It only activates when using the module
* as a DLL.
*
* 2. Create a DLL file with just the module source file (and any associated
* files). Be sure to link it against the ApacheCore.lib created when
* compiling ApacheCore.dll. You may also have to tweak the settings to
* find all of the Apache includes files correctly. After creating the
* DLL, follow the above instructions to load it into Apache.
