SignalNotifier SignalNotifier SignalNotifier Class
Definition
Runs a method when an event or semaphore is signaled. A timeout value can also be specified, causing the delegate to run after the time span has elapsed if the named event does not occur (or if the semaphore does not reach a signaled state).
Note
The ThreadPool API is supported for desktop as well as Windows Store apps.

Methods
AttachToEvent(String, SignalHandler) AttachToEvent(String, SignalHandler) AttachToEvent(String, SignalHandler)
Attaches a SignalHandler delegate to an event. The delegated method will run the next time the event occurs.

- name
- PlatForm::String String String
Indicates the event that causes the method to run.
- handler
- SignalHandler SignalHandler SignalHandler
Indicates the method that will run in response to the event.
The resulting SignalNotifier object.

AttachToEvent(String, SignalHandler, TimeSpan) AttachToEvent(String, SignalHandler, TimeSpan) AttachToEvent(String, SignalHandler, TimeSpan)
Attaches a SignalHandler delegate to an event. The delegated method will run if the event occurs or the time span elapses, whichever comes first.

- PlatForm::String String String
Indicates the event that causes the method to run.
- handler
- SignalHandler SignalHandler SignalHandler
Indicates the method that will run in response to the event, or when the time span elapses, whichever comes first.
- timeout

Indicates the amount of time to continue waiting for the event before running the handler method.

AttachToSemaphore(String, SignalHandler) AttachToSemaphore(String, SignalHandler) AttachToSemaphore(String, SignalHandler)
Attaches a SignalHandler delegate to a named semaphore. The delegated method will run when the named semaphore is signaled.
