and how would you make this source compatible with the static
binding version?
I guess it is not possible
extern(C):
version(Dynamic) {
__gshared wl_interface *wl_display_interface;
}
else {
extern __gshared wl_interface wl_display_interface;
}
// use case: some_func expects a pointer to wl_interface
// the C version is using addressof operator, (as do the static D
bindings)
some_func(&wl_display_interface);
