Re: [Haskell-cafe] named pipe interface

Quoth "Serge D. Mechveliani" , [ ... why in Haskell instead of FFI ... ]

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?

The GHC Haskell library makes some compromises with normal I/O functionality for the sake of its runtime thread system. As difficult as named pipes can be in any case, they can be even trickier in GHC Haskell for this reason. I didn't suggest an FFI approach myself, in my previous follow-up, only because if you haven't worked with the FFI it's a significant initial investment, but I believe it's what I would do. (If I were somehow compelled to used named pipes.) Donn
