Hi,
I am new to Windows Programming. Can anyone tell me whether the calling thread is blocked on SetEvent() function? Or atleast is it ensured that the thread(s) waiting on the Event set by Set Event() function are scheduled ahead of the thread calling the SetEvent() function?
Thanks,
Abhijit
No it is not, why should it be?the calling thread is blocked on SetEvent
With multiple threads waiting for the same event - behavior will be different for Manual reset and automatic reset events... (all or only one random thread will be resumed)Or atleast is it ensured that the thread(s) waiting on the Event set by Set Event() function are scheduled ahead of the thread calling the SetEvent() function?
All resumed threads will be scheduled in the regular mode... And no one will give you a guarantee that it (they) will be scheduled on the same CPU as the thread calling SetEvent
All problems in computer science can be solved by another level of indirection,
except for the problem of too many layers of indirection.

Thanks for the info.
I agree with you for multiple processor environment. What about uni processor environment?
What about it? All resumed threads are scheduled according to the scheduler model of the Windows...What about uni processor environment?

Events are not meant for thread synchronization...
For that you need critical sections, semaphores or mutexes.
Events are used to signal when an event occurs.
