Creates a TPL Task that returns true
when a WaitHandle is signaled or returns false
if a timeout occurs first.
public static System.Threading.Tasks.Task<bool> ToTask (this System.Threading.WaitHandle handle, int timeout = -1, System.Threading.CancellationToken cancellationToken = default);
static member ToTask : System.Threading.WaitHandle * int * System.Threading.CancellationToken -> System.Threading.Tasks.Task<bool>
<Extension()>
Public Function ToTask (handle As WaitHandle, Optional timeout As Integer = -1, Optional cancellationToken As CancellationToken = Nothing) As Task(Of Boolean)
Parameters
- handle
- WaitHandle
The handle whose signal triggers the task to be completed. Do not use a Mutex here.
- timeout
- Int32
The timeout (in milliseconds) after which the task will return false
if the handle is not signaled by that time.
- cancellationToken
- CancellationToken
A token whose cancellation will cause the returned Task to immediately complete in a canceled state.
Returns
A Task that completes when the handle is signaled or times out, or when the caller's cancellation token is canceled.
If the task completes because the handle is signaled, the task's result is true
.
If the task completes because the handle is not signaled prior to the timeout, the task's result is false
.
Remarks
The completion of the returned task is asynchronous with respect to the code that actually signals the wait handle.
