Description

The #resource_string function returns the SCREEN_RESOURCES property from the root window of the actual screen. The property is converted from type STRING to the current locale. The conversion is identical to that produced by Display::mb_text_property_to_text_list for a single element STRING property. The property value must be in a format that is acceptable to X11::rm_get_string_database. If no property exists, empty string is returned.
