multithreading level loading

i want to write a world loading class where i''m dynamically loading/unloading chunks of the level as the cahracter moves around the world so that the "next" section is always loaded in memory and sections which are no longer needed are removed from memory. This will obviously require multithreading. Where is there a good tutorial on multithreading in VC++ with DirectX. info@hero-interactive.com SkullOne - Hero Interactive http://www.hero-interactive.com
