* @title: Dynamic Loading of Modules
* @short_description: portable method for dynamically loading 'plug-ins'
*
* These functions provide a portable way to dynamically load object files
* (commonly known as 'plug-ins'). The current implementation supports all
* systems that provide an implementation of dlopen() (e.g. Linux/Sun), as
* well as Windows platforms via DLLs.
*
* A program which wants to use these functions must be linked to the
* libraries output by the command `pkg-config --libs gmodule-2.0`.
*
* To use them you must first determine whether dynamic loading
* is supported on the platform by calling g_module_supported().
* If it is, you can open a module with g_module_open(),
* find the module's symbols (e.g. function names) with g_module_symbol(),
* and later close the module with g_module_close().
* g_module_name() will return the file name of a currently opened module.
*
* If any of the above functions fail, the error status can be found with
* g_module_error().
*
* The #GModule implementation features reference counting for opened modules,
* and supports hook functions within a module which are called when the
* module is loaded and unloaded (see #GModuleCheckInit and #GModuleUnload).
*
* If your module introduces static data to common subsystems in the running
* program, e.g. through calling
* `g_quark_from_static_string ("my-module-stuff")`,
* it must ensure that it is never unloaded, by calling g_module_make_resident().
*
* Example: Calling a function defined in a GModule
* |[<!-- language="C" -->
* // the function signature for 'say_hello'
* typedef void (* SayHelloFunc) (const char *message);
*
* gboolean
* just_say_hello (const char *filename, GError **error)
* {
* SayHelloFunc say_hello;
* GModule *module;
*
* module = g_module_open (filename, G_MODULE_BIND_LAZY);
* if (!module)
* {
* g_set_error (error, FOO_ERROR, FOO_ERROR_BLAH,
* "%s", g_module_error ());
* return FALSE;
* }
*
* if (!g_module_symbol (module, "say_hello", (gpointer *)&say_hello))
* {
* g_set_error (error, SAY_ERROR, SAY_ERROR_OPEN,
* "%s: %s", filename, g_module_error ());
* if (!g_module_close (module))
* g_warning ("%s: %s", filename, g_module_error ());
* return FALSE;
* }
*
* if (say_hello == NULL)
* {
* g_set_error (error, SAY_ERROR, SAY_ERROR_OPEN,
* "symbol say_hello is NULL");
* if (!g_module_close (module))
* g_warning ("%s: %s", filename, g_module_error ());
* return FALSE;
* }
*
* // call our function in the module
* say_hello ("Hello world!");
*
* if (!g_module_close (module))
* g_warning ("%s: %s", filename, g_module_error ());
* return TRUE;
* }

* @module_name: the name of the module
*
* A portable way to build the filename of a module. The platform-specific
* prefix and suffix are added to the filename, if needed, and the result
* is added to the directory, using the correct separator character.
*
* The directory should specify the directory where the module can be found.
* It can be %NULL or an empty string to indicate that the module is in a
* standard platform-specific directory, though this is not recommended
* since the wrong module may be found.
*
* For example, calling g_module_build_path() on a Linux system with a
* @directory of `/lib` and a @module_name of "mylibrary" will return
* `/lib/libmylibrary.so`. On a Windows system, using `\Windows` as the
