Synchronous I/O Programming
Synchronous programming simply waits for a call to return. This is fast and efficient from the programmer's point of view but in an environment like Windows where many programs are running at once, it can cause problems. Whenever possible, use Asynchronous I/O Programming Techniques.
Note For driver developers using Microsoft Vista, this is not as serious a problem. For more information about synchronous programming in Vista, see Restricting Waits in Vista.
