winrt::resume_after function (C++/WinRT)

  • Article

A helper function—for use within a coroutine—that returns control to the caller, and then resumes execution on a thread pool thread after a delay.

For more info, see Concurrency and asynchronous operations.

Syntax

inline auto resume_after(winrt::Windows::Foundation::TimeSpan duration) noexcept;

Parameters

duration

The duration of the delay.

Return value

An object that you can co_await.

Remarks

You can use the functions and operators in the std::chrono and std::literals::chrono_literals namespaces to create TimeSpan values conveniently.

co_await winrt::resume_after(std::chrono::milliseconds(250));

using namespace std::literals::chrono_literals;
co_await winrt::resume_after(250ms);
