I have also run into this same problem a while ago.

There is already a C-function for handling that case in the
OCaml-runtime (unix_error). You only need to write a C-wrapper that
converts the arguments to this function appropriately, and define an
"external"-function in OCaml. Then you can raise the corresponding
Unix_error-exceptions by passing the error code and other arguments
(i.e. name of associated Unix-call and arguments).
But I agree, it would be a very good idea to expose this function in
the standard Unix-module (hint, hint!)...
Best regards,
Markus
