public unowned string get_prgname ()
Gets the name of the program.
This name should not be localized, in contrast to get_application_name.
If you are using
GApplication the program name is set in
g_application_run. In case of GDK or GTK+ it is set in
gdk_init, which is called by
gtk_init and the
GtkApplication::startup handler. The program name is found
by taking the last component of
the name of the program, or null if it has not been set yet. The returned string belongs to GLib and must not be modified or freed.
