Header

#include <xtd/threading/wait_or_timer_callback>

Namespace

xtd::threading

Library

xtd.core

Parameters

state	An object containing information to be used by the callback method each time it executes.
timed_out	true if the xtd::threading::wait_handle timed out; false if it was signaled.

Remarks

xtd::threading::wait_or_timer_callback represents a callback method that you want to execute when a registered wait handle times out or is signaled. Create the delegate by passing your callback method to the xtd::threading::wait_or_timer_callback constructor. Your method must have the signature shown here.

Create the registered wait handle by passing the xtd::threading::wait_or_timer_callback delegate and a xtd::threading::wait_handle to xtd::threading::thread_pool::register_wait_for_single_object. Your callback method executes each time the xtd::threading::wait_handle times out or is signaled.

If you want to pass information to your callback method, create an object that contains the necessary information and pass it to xtd::threading::thread_pool::register_wait_for_single_object when you create the registered wait handle. Each time your callback method executes, the state parameter contains this object.
