How does one use pass by reference functions using the ffi?

Hello FFI experts,
Say I have a function somewhere in c land with the following declaration:
void doStuff( int &a, int &b);
What would the appropriate Haskell wrapper for this function look like?
I'm looking to construct a haskell function of the type:
doStuff :: Int -> Int -> IO( (Int,Int) )
There weren't any relevant results when searching `"pass by reference"
haskell ffi` in google.
Thanks in advance,
David J. Sankel
