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
