Thank you, Paolo!

I've made the following:

gst_xcb_setup_roots_iterator (const xcb_setup_t *setup,
{       if (setup&&  iter)
                *iter = xcb_setup_roots_iterator (setup);

in my shared library and

Xcb class>>  setupRootsIterator: aSetup ptr: iterPtr [
     <cCall: 'gst_xcb_setup_roots_iterator' returning: #void args:
#(#cObject #{XcbScreenIterator})>

in the gst binding.. Now it works!!

Yes, that's exactly what I meant.  Nice that it works! :-)
