Hi list, I am working on some new bindings for a library which hides the declaration of a struct. Basically, all the public header defines is
typedef struct foo foo; All functions of the library return pointers to `foo` or consume pointers to `foo`. I reckon that it prevents users of the library to copy the structure or mess with its members. I do not know what's the preferred way to handle this situation in ctypes. I would really like to use `abstract`, but in that particular case, I should really not be able to provide the size nor the alignement of the struct. I could use void pointers to implement foo pointers, but this seem a bit error prone (minor variation: use magic to expose `unit ptr typ` as `foo ptr typ` with `foo` a fresh type). Any pointers welcome! Best, Thomas _______________________________________________ Ctypes mailing list [email protected] http://lists.ocaml.org/listinfo/ctypes
