How to: Creating a thread pool task queue

Example

The following example shows how to create a task queue that dispatches both work and completion callbacks on the system thread pool.

void CreatingTaskQueue()  
{  
    XTaskQueueHandle queue;  
 
    HRESULT hr = XTaskQueueCreate(  
        XTaskQueueDispatchMode::ThreadPool,  
        XTaskQueueDispatchMode::ThreadPool,  
        &queue);  
 
    if (FAILED(hr))  
    { 
        printf("Creating queue failed: 0x%x\r\n", hr);  
        return;  
    }  
 
    SubmitCallbacks(queue); 
 
    // Wait a while for the callbacks to run.  
    Sleep(1000);  
 
    XTaskQueueTerminate(queue, true, nullptr, nullptr);  
}  

Sample output

Worker invoked on thread 11440. Cancel? 0. 
Completion invoked on thread 11440. Cancel? 0.
