+ * This method will not be called in normal use, however it may be
+ * called when probing existing modules and recording which extension
+ * points that this model is used for. This means we won't have to
+ * load and initialize this module unless its needed.
+ *
+ * If this function is not implemented by the module the module will

+ * Note that a module need not actually implement all the extension
+ * points that g_io_module_query() returns, since the exact list of
+ * extension may depend on runtime issues. However all extension
+ * points actually implemented must be returned by g_io_module_query()
+ * (if defined).
+ *
+ * When installing a module that implements g_io_module_query() you must
+ * run gio-querymodules in order to build the cache files required for
+ * lazy loading.
+ *
+ * Returns: (transfer full): A %NULL-terminated array of strings,
+ * listing the supported extension points of the module. The array
+ * must be suitable for freeing with g_strfreev().
