Provide module types? (Question)

[jsoo1]

This is more a question than anything else. Is it possible to create module types for these posix modules? I am working on a library and I am wondering how I can let the user bring their own c libraries. It would be nice to refer to some ocaml type or function in the library and defer to the library user to bring their own platform-specific ffi. Maybe this is an ill formed thought and I don’t know how to use your library. Thanks for your work! So far it works nicely!
