If I open a file using "openFile" from the IO module
(x <- openFile "foo.txt" ReadMode)
and convert it to a String via hGetContents
(y <- hGetContents x)
and finally try to print the file on the screen
(putStrLn y)
I'll get a strange result if the file contains the character 1A-hexadecimal

Hi Patrick.
This is probably because you need to build HDirect in two stages - once
without typelibrary support, and once with. Here is the process I used to
build HDirect 0.17 with ghc 4.08 under NT (much is probably irrelevant as I
think some of these problems have been sorted by Sigbjorne):

Is the posix library (-package posix) supposed to be supported on
Windows? If not (as I expect to have confirmed), what are the
alternatives for process control on Windows?

I am trying to build a Haskell COM component with HDirect (from
http://www.galconn.com/~sof/hdirect-0.18-src.tar.gz) and "ghc 5.02". I have
problems generating the type library: it is simply not created. Even the
comserv example is not working because of the same problem. Could that be a
bug in t

Actually I don't need to convert the pointers, do I? If I have (Storable
SomeLinkedList), I can just declare
