** [patches:#525] consistent arguments to canvas_properties**

**Status:** open
**Group:** bugfix
**Labels:** dev 
**Created:** Wed Jun 25, 2014 09:53 AM UTC by IOhannes m zmölnig

**Owner:** Miller Puckette

this patch changes the signature of `canvas_properties()` to

    ::C
    void canvas_properties(t_gobj *z, t_glist *canvas);

this fixes the problem, that canvas_properties was declared with an argument `t_gobj*` but then was implemented with an argument `t_glist*` (which triggered an error about undefined behaviour)

it also makes the function is a proper `t_propertiesfn` (by adding an unused 2nd argument), thus avoiding a typecast (which hid the above problem)
