- * 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.
