Hi, I'm on to it. Let's presume for the moment that I will solve a simpler problem, before I get the full task done. Say, for argument's sake, that I want to make the function printObj() available in Haskell, where: void printObj (StgClosure *obj); (as defined in and exported from rts/Printer.c) In Haskell I want to reflect this as: printObj :: a -> IO () Alistair mentioned that I could use the FFI to access some C code in the RTS. My intuition would have been to go about adding a primop as described in /ghc/compiler/prelude/primops.txt (ie without calling through the FFI). My trouble is I can't find any examples that are greatly similar to what I want to do. My question is: should I implement it through the FFI or as a primitive ala primops.txt? Perhaps they amount to much the same thing. Cheers, Bernie. _______________________________________________ Glasgow-haskell-users mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
