Not an  OCaml "program". I simply write C DLLs embedding my Caml code as
described in
18.7.5  Embedding the Caml code in the C code

Nothing automatic. I manually write all C functions, have them call OCaml
callbacks, etc.
If this is actually what you have in mind, I can write and post one
minimalistic example.

It is possible to have a tool to turn one OCaml library (CMA/CMXA) into one
shared library.
See ODLL, from N. Canasse in the hump.
