Yes, but the functions have now a caml_ prefix. Make sure that there is no interaction whatsoever with ocaml's runtime system (e.g. ocaml value allocation) between the two calls. Note also that in case you need to use some caml value after the leave call you have to declare it with a CAMLparam macro as it may move during the blocking section even if the stub itself doesn't allocate.
