Hi, The Foreign Function Interface (FFI) is your friend for these tasks: http://www.cse.unsw.edu.au/~chak/haskell/ffi/ On the haskell.org web page, under "libraries and tools" there are links to a number of tools to help you connect your C & haskell programs. The GreenCard and c->haskell tools seem to be used by a number of people. Alastair Reid's Guide to Haskell's Foreign Function Interface, http://www.reid-consulting-uk.ltd.uk/docs/ffi.html is a good place to start. It has some comparison of the various tools.

Does Haskell have some mechanism that allows it to link to C, or other imperative languages?
I know, you could use the IO Monad to do it...using stdin and stdout as pipes to any other program. But is there a way to link Haskell into a C program?
Thanks again for the help for a newbie... Russ _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
