Subject: Wrapping OCaml function returning a variant
Date: Wed, 28 Mar 2007 12:33:46 +0100 [thread overview]
Message-ID: <E888843F-390B-49FB-82E5-662088922B56@gmail.com> (raw)
Is there an example of returning a variant from OCaml into C somewhere?
It's a regular variant, declared like this
type morpher_output =
| Success of string
| Error of string * int * int * int
The other issue is that I don't know how to deal with strings
allocated in OCaml. Will they be collected automatically?
The strings _must_ be allocated in OCaml but I can guarantee that
they will not be modified in the C code. Any suggestions on how to
deal with this?
Thanks, Joel
