The main thread initializes Counter, launches the task threads, and waits for the signal that they are all done by calling the TEvent::WaitFor method.

Windows provides a number of additional features that relate to threads and synchronization, and we discuss some of these here. Thread: join() (Using join() to wait for threads to finish) /* * Output: New thread: Thread[One,5,main] New thread: Thread[Two,5,main] New thread: Thread[Three,5,main] Two: 5 Thread One is alive: true Thread Two is alive: true Thread Three is alive: true Waiting for threads to finish.

It does this by calling function WaitForMultipleObjects() . Calling _beginthread() looks more convenient because it takes fewer parameters and clean up the handle after the thread exits, however, it is better to use _beginthreadex() . After the thread is created, the call blocks waiting for the thread to finish creating the message queue using WaitForSingleObject(m_hThreadStarted, MAX_WAIT_TIME). In the following illustration, assume a thread group with 50 threads where the size of the group is given by (5,5,2).

The CreateThread() function create the thread when attributes are passed as parameters.

Using the Code. Win32 Thread Support. The key here is that thread handles are signalled when the thread exits.

A pointer to a variable to receive the thread termination status.

In a deadlock, both threads will wait for each other to finish but neither thread will finish until the other finishes first, causing them to become locked. So, the main thread must wait for the threads it created to complete before it exits the main() function. For more information, see Thread Security and Access Rights. It is simple because under Win32 thread handles represent kernel objects which you can wait on. The handle must have the THREAD_QUERY_INFORMATION or THREAD_QUERY_LIMITED_INFORMATION access right. Index a particular thread, within a thread group using a 3D vector given by (x,y,z).

WaitFor waits a specified time period for the signal to be set and returns one of the values in the table below.. This is a short function that will run another program as if from the command line, wait for it to finish, and return the process's exit code. The attributes are stack size, a flag to ensure blocking state during thread start, function Summation and its parameters. As Python runs on many operating systems, the Python thread support is limited to a reasonable subset of what a platform can be expected to provide in the way of threading. A single thread is identified from a thread group with 50 threads in it, using the vector (4,1,1).

ThreadWin::CreateThread() creates a thread using the Win32 CreateThread() API. The main thread entry function is ThreadWin::RunProcess(). The problem was to wait these actions to be terminated, to first analyse the result, and then display or not the box. The solution to this problem is to use one, or more, of the synchronization objects provided by Windows. The wait function blocks when the object is in an unsignaled state, while the wait function resumes when the object reaches a signaled state. Native Win32 Threads This blog is for WIN32 and MFC guys; The wait functions are used to block a thread from executing till a kernel object reaches a certain state.

So simply wait on the two thread handles, using either a single call to WaitForMultipleObjects() or two calls to WaitForSingleObject(). lpExitCode.

The WaitForSingleObject() make parent thread to go to blocking state and wait until Summation thread is completed. The actions made were done with others threads. Windows Server 2003 and Windows XP: The handle must have the THREAD_QUERY_INFORMATION access right.

The following code example shows how the main thread launches the task threads and resumes when they have completed. The first method I've found was very simple and worked very well, but only when this …
