I have a C function that, for simplicity, has its definition as something like:
> void myCFun(FILE *fd); I have a Handle I've opened in Haskell using openFileEx and would like to pass this to the function. I've tried a bunch of things, the most recent being: > foreign import ccall "myHFile.h myCFun" c__myCFun :: Ptr CInt -> IO () > myCFun :: Handle -> IO () > myCFun (FileHandle handleMV) = do > h__ <- readMVar handleMV > ptr <- malloc > poke ptr (toCInt $ haFD h__) > c__initVars ptr i've also tried it with just CInt -> IO (), without the ptr, but that doesn't work either. Surely someone has done this at some point...or is it even possible (please say it is)... - Hal -- Hal Daume III | [EMAIL PROTECTED] "Arrest this man, he talks in maths." | www.isi.edu/~hdaume _______________________________________________ Glasgow-haskell-users mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
