Thank you, Paolo!

I've made the following:

void
gst_xcb_setup_roots_iterator (const xcb_setup_t *setup,
                                                          xcb_screen_iterator_t 
*iter)
{       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!!

Dmitry
