I want child thread to acquire a lock as soon as it becomes alive. But at the time of initialization of child thread, running thread is parent thread. At the time of initialization, I want child thread to acquire the lock.. How can I do that?

Is there any other way , by which I can do that?

Child requests lock, which causes task switch and gives the parent the opportunity to release it, right?

Otherwise, post the original cause of the problem and why you want to solve it like this.
