Creating a thread and blocking its execution
Hello, I use boost::thread as follow: mp_Thread = new boost::thread(boost::bind(CSubsystem::TaskWrapper, this)); to create a thread in an initialization method. I observe that this thread gets to run before my initialization method has completed its execution. I would like to create a thread from this initialization method, and wait for it to execute until the whole initialization process it done. Is it possible to create a thread in suspended mode, and then release it once the system is ready? Or do I need to use a synchronization mechanism like a semaphore to release it? Jean-Sebastien

I would use a condition variable plus a boolean state (a primitive event) that is passed to the thread-function upon creation (utilizing boost::bind). thread waits for the condition to be signaled. the initialization routine updates the state and notifies the condition upon completion. If you need this pattern frequently, I'd suggest to extract that logic from CSubsystem::TaskWrapper into common class. Best regards, Christoph

What prevents you from creating the thread as the last step in your initialization method?
