Venting to outdoors - clearances to windows


Does anyone know if there are any code requirements that state the minimum distance from outdoor vents (range hood) to openable windows?

I would like to vent my range hood straight back through an exterior wall, but the exterior outlet would be about 4 feet from a bathroom window. My other alternative is to go up through a cabinet and then through the roof, but this would be a lot more difficult.
