Hello everyone... Is there a way to give a piece of code exclusive access to the CPU without fear of interruption from Windows? Something similar to a critical section, but across processes -- not just threads. And in user space... not kernel level or anything. If not, I imagine it's for stability reasons... but I figured there'd at least be *something*. Any help would be very appreciated... thanks! - Som (I posted this in the Visual C++ because I'm using C to program this...)
