How API call Windows Deriver/The mapping API to Driver function
-
Hi all, I am newbie to Window Driver programming. So, my question that I concern is how the API call exactly Driver functions. E.g.: User application call an API function, then API function call Windows Driver. The question is how the API function maps to Driver function or call the driver correctly, especially there are many drivers for one device. As of my thinking, the driver must conform to the rule that Microsoft define? Pls answer me in the soonest time and Thank you very much.
