Description

Functions

gnome_rr_error_quark ()

GQuark
gnome_rr_error_quark (void);

Returns the GQuark that will be used for GError values returned by the GnomeRR API.

Returns

a GQuark used to identify errors coming from the GnomeRR API.


gnome_rr_screen_new ()

GnomeRRScreen *
gnome_rr_screen_new (GdkScreen *screen,
