Can you please suggest what is holding the application from execution about the following deadlock pattern? I could see the WaitForMultipleObjectsEx function being called which is making it to wait for an object. But I am not able to understand what type of object it is waiting for? How this deadlock can be resolved?
Thanks in advance
