+/**
+ * @brief Gets the preinitialized window object.
+ *
+ * @details This function returns a window object that is created by the framework.
+ *          You can get the handle of the preinitialized window using this API.
+ *          Because the window is preinitialized, you can speed up your application's launching time.
+ * @since_tizen 3.0
+ * @remarks When you set @a preinit-window attribute of the @a ui-application tag as "#true" in the tizen-manifest.xml,
+ *          the framework creates an window for your application beforehand.
+ *          Note that the preinitialized window is created using elm_win_add() as #ELM_WIN_BASIC type.
+ *          If you want to use a window of other types, you cannot use this API.
+ *
+ *          The specific error code can be obtained using the get_last_result() method.
+ *          Error codes are described in Exception section.
+ * @param[in] win_name The name to be set for the preinitialized window
+ *
+ * @return A @a window object on success,
+ *         otherwise @c NULL
+ * @exception TIZEN_ERROR_NONE Success
+ * @exception TIZEN_ERROR_INVALID_PARAMETER Invalid parameter
+ * @exception TIZEN_ERROR_IO_ERROR I/O error
