Hi all, 

I am trying to use the canvas_makefilename() function in g_canvas.c

I am calling it like this: 

static void lilypond_write(t_lilypond *x, t_symbol *s) {
    char buf[MAXPDSTRING];
    canvas_makefilename(x->x_canvas, s->s_name, buf, MAXPDSTRING);

but when I send the object a message such as [write test.txt( or similar, I get:

error: consistency check failed: canvas_getenv
Bus error: 10

The method is set up like this:
	class_addmethod(lilypond_class, (t_method)lilypond_write, gensym("write"), A_SYMBOL, 0);

Anybody has any suggestion?



PS Sorry for pestering everyone with this, but there is little documentation on some of the functions in Pd. Perhaps this thread belong in the Pd-Dev list?
