-Wincompatible-pointer-type for functions taking a pointer

[David Smith]

Hey,

I'm trying to use a C library (libwayland) from ATS (still), and now I finally got everything working, but I'm getting a few warnings related to function pointers.

I got the following code

typedef
wl_registry_listener = $extype_struct "struct wl_registry_listener" of
  {
    global= (ptr, !wl_registry1, uint32, string, uint32) -<1> void,
    global_remove= (ptr, !wl_registry1, uint32) -<1> void

  }

However it complains about incompatible pointer types, as ATS seems to use `void *` for the ptr, the registry and the string.

Is there any way I can get rid of this warning or do I just have to live with it?

Thanks in advance!

Yes, you can.

Please take a look at how 'charptr' is handled in the following simple example:

Alright, I think I figured it out, thank you!
