on the subject of interfacing OCaml with C/C++, it is not clear
to me whether and how OCaml objects of sum types can be passed
to a C/C++ function. For example, suppose I have the declaration
type expr =
Variable of int
| Coefficient of int
| UPlus of expr
| UMinus of expr
| Sum of (expr * expr)
| Difference of (expr * expr)
| Product of (expr * expr)
What is the best way to pass an expr object to C/C++?
How can C/C++ code visit such a structure?
Many thanks for your time and patience,
Claudio
