#define CAIRO_SURFACE_DESTROY

(

surf

)

Value:

    do {\
        if ((surf) != NULL) { \
            cairo_surface_destroy((surf)); \
            (surf) = NULL; \
        } \
    } while (0)

If surf is not NULL, calls cairo_surface_destroy() on it and resets the surf pointer to NULL afterwards.
