Hi Remi,

I am happy to finally announce cinvoke 0.1, a binding to the C library cinvoke[1], allowing functions to be loaded and called whose names and types are not known before run-time.

As the author of the libffi package (http://hackage.haskell.org/package/libffi-0.1) which does a similar thing, could you say when it would be appropriate to use one or the other package?

Cheers, Max

Of course:

- libffi doesn't do library/function loading; you'll need to use  System.Posix.DynamicLinker or System.Win32.DLL for that.  cinvoke will not only load your libraries and functions,  but even collect the garbage afterwards. - Things seem to have changed, but back when I first looked at  cinvoke, getting libffi to run under windows didn't seem too  realistic. - If you need to pass C structs (by value), you'll have to use  libffi: cinvoke doesn't support them at all. - The current version of libffi is not exception safe (I do have  some code lying around here though...) - cinvoke is actually haddockized (although hackage still hasn't  generated the docs, apparently).

It's reporting a build failure.

Groeten, Remi
