Are you sure you need sys/io.h? What are you using from it? As far as I can see it doesn't define anything that you might want to use, just functions for reading and writing bytes from/to the non-portable unix io ports feature (aka /dev/port).
yes, only this _commit really. and how should i import this fsync instead of _commit so that this import will work on all unix platforms (supported by ghc and other compilers)?
is the following enough:
foreign import ccall unsafe "unistd.h fsync" c_commit :: CInt -> IO CInt
I think that should do. It's defined in POSIX.1b so you should be able to rely on it being defined in that header file on all POSIX systems.
? or it's better to import it using HsBase.h?
Well that's GHC-only as far as I know. Duncan
