Threads execution time

[pavellus]

I would like to know how Windows resolve thread execution time in the following three situations:

- if thread execute an empty while loop for example while (true) {;}
- if thread execute a loop waiting for a key pressed for example while (true) { if key_pressed() = true { break; } }
- if thread wait for synchronized resource for example object that is used by another thread.

Do windows execute every thread with the same time given a priori or
detect situations where thread is waiting for special signal and switch to the next thread?

Is any documentation describing windows algorithm of threads and processes scheduler?

Multithreading applications in win32 is a good resource.

Threads like processes have priority levels, and a base and dynamic priority.

These pages have some information that may help.
