wait_callback

using xtd::threading::wait_callback = typedef delegate<void(std::any)>

Represents a callback method to be executed by a thread pool thread.

using wait_callback = xtd::action<std::any>

Header

#include <xtd/threading/wait_callback>

Namespace

xtd::threading

Library

xtd.core

Parameters

state

An object containing information to be used by the callback method.

Remarks

xtd::threading::wait_callback represents a callback method that you want to execute on a xtd::threading::thread_pool thread. Create the delegate by passing your callback method to the xtd::threading::wait_callback constructor. Your method must have the signature shown here.

Queue the method for execution by passing the xtd::threading::wait_callback delegate to xtd::threading::thread_pool::queue_user_work_item. The callback method executes when a thread pool thread becomes available.

If you want to pass information to the callback method, create an object that contains the necessary information and pass it to the xtd::threading::thread_pool::queue_user_work_item(xtd::threading::wait_callback, xtd::object&) method as the second argument. Each time the callback method executes, the state parameter contains this object.

For examples that use the xtd::threading::wait_callback delegate, see the xtd::threading::thread_pool::queue_user_work_item method.
