People,

(I wonder: is this for  beginners@haskell.org ?)

I don't think so.

I need to organize a  string interface  for a Haskell function Main.axiom  and a C program                            fifoFromA.c

via a pair of  named pipes  (in Linux, UNIX). The pipes are created before running, by the commands   > mkfifo toA                                                        > mkfifo fromA

Main.axiom  outputs a  string  to  toA  and inputs the respond string                                            from  fromA  as the result. fifoFromA  inputs a string from  toA,           converts it to the string  resStr,  outputs resStr to  fromA.

Now that seems interesting, but just to be clear : did you choose this solution (and why won't you use the FFI instead) or is this just to see how to work it out ?

Because it is a direct and the simplest approach. Why does one need a foreign language, if all the needed functions are in the standard Haskell library? Sergei.
