You have to use readBinaryFile instead of readFile.
I had the same trouble as well.

I finally implemented accessing single characters in C and did use ffi
because I didn't know haw to do this i haskell properly. ( using
peek/poke functions 4 bytes got written (wihch is annotateted somewhere
) If you are interested I can sent you the modified ByteString package.

If someone can tell me which haskell function to use to set a random
char in a memory buffer I would be pleased ..
