Add support for unsafe ocaml arguments. #607

Closed toots closed 4 years ago

toots commented 5 years ago

If I'm not mistaken, it should be possible to:

Register a string or bytes buffer via Root.register
Pass this value to a C callback via ocaml_{string,bytes}_start
Once the callback has returned, release the root via Root.release

This PR adds this possibility by introducing ocaml_unsafe_{string,bytes} (and the yet unexposed ocaml_unsafe_float_array).

Let me know what you think!
