What is a ForeignObj?
I call a C function, which gives me a cString :: Ptr CChar, and it's my responsibility to free it when I've finished with it. So I convert it to a ForeignPtr: foreignPtr <- mkForeignPtr cString and then always refer to the pointer via foreignPtr. When foreignPtr is garbage collected the space is freed. So how do I do this with your proposal? _______________________________________________ FFI mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/ffi
