+# How to: Create a task that completes after a delay
 
 This example shows how to use the [concurrency::task](../../parallel/concrt/reference/task-class.md), [concurrency::cancellation_token_source](../../parallel/concrt/reference/cancellation-token-source-class.md), [concurrency::cancellation_token](../../parallel/concrt/reference/cancellation-token-class.md), [concurrency::task_completion_event](../../parallel/concrt/reference/task-completion-event-class.md), [concurrency::timer](../../parallel/concrt/reference/timer-class.md), and [concurrency::call](../../parallel/concrt/reference/call-class.md) classes to create a task that completes after a delay. You can use this method to build loops that occasionally poll for data, introduce timeouts, delay handling of user input for a predetermined time, and so on.

-The `cancel_after_timeout` function builds on the `complete_after` function to cancel a task if that task does not complete before a given timeout. The `cancel_after_timeout` function creates two tasks. The first task indicates success and completes after the provided task completes; the second task indicates failure and completes after the specified timeout. The `cancel_after_timeout` function creates a continuation task that runs when the success or failure task completes. If the failure task completes first, the continuation cancels the token source to cancel the overall task.

 ## Example: Compute count of prime numbers
 
-The following example computes the count of prime numbers in the range [0, 100000] multiple times. The operation fails if it does not complete in a given time limit. The `count_primes` function demonstrates how to use the `cancel_after_timeout` function. It counts the number of primes in the given range and fails if the task does not complete in the provided time. The `wmain` function calls the `count_primes` function multiple times. Each time, it halves the time limit. The program finishes after the operation does not complete in the current time limit.

-When you use this technique to cancel tasks after a delay, any unstarted tasks will not start after the overall task is canceled. However, it is important for any long-running tasks to respond to cancellation in a timely manner. For more information about task cancellation, see [Cancellation in the PPL](cancellation-in-the-ppl.md).
