Arguments

cr

[Cairo] a Cairo

Value

[CairoFontFace] the current font face. To keep a reference to it, This function never returns NULL. If memory cannot be allocated, a special "nil" CairoFontFace object will be returned on which cairoFontFaceStatus returns CAIRO_STATUS_NO_MEMORY. Using this nil object will cause its error state to propagate to other objects it is passed to, (for example, calling cairoSetFontFace with a nil font will trigger an error that will shutdown the Cairo object).
