Why not use ocaml's module and fiunctor capacity, and just output a functor
taking the callbacks as argument, and generating the interface ? 

This way, you don't overwrite any user written files, and the user just has to
write the callbacks by himself (maybe presenting him with an appropriate
module type to take example from ?).

This is one of the things you can do with ocaml that you cannot do in C.

Also, you could also simply parse the existing ocaml code and just change the
function that need changing, but this is more long, and not as elegant.
