Here's a C wrapper, if you want/need to use that version of the code instead:

/* C wrapper for dealing with C functions that return structs */ 
#include <xcb/xcb.h> 
xcb_screen_iterator_t * eu_xcb_setup_roots_iterator(const xcb_setup_t * setup) 
{ 
	xcb_screen_iterator_t iter = xcb_setup_roots_iterator(setup); 
	return &iter; 
}
