Re: [Haskell-cafe] Bit fiddling

* robert dockins:

Probably you have seen this already, but I thought I'd mention it on the off-chance you missed it:

http://www.haskell.org/ghc/docs/latest/html/libraries/base/Data.Bits.html http://www.haskell.org/ghc/docs/latest/html/libraries/base/Data.Word.html

Probably you'll want to think about an IOUArray of Word8, or something similar.

IOUArray looks indeed interesting, thanks. How can I pass such objects (in particular of type IOUArray Int Word8) to a C routine, preferably as a void */size_t combination?
