setPrgname

Sets the name of the program. This name should not be localized, in contrast to [glib.global.setApplicationName].

If you are using #GApplication the program name is set in [gio.application.Application.run]. In case of GDK or GTK it is set in [gdk.global.init_], which is called by [gtk.global.init_] and the #GtkApplication::startup handler. The program name is found by taking the last component of argv[0].

Since GLib 2.72, this function can be called multiple times and is fully thread safe. Prior to GLib 2.72, this function could only be called once per process.
