WebMar 9, 2024 · Previous: Handling Async Completion Now that we’ve explored the async interfaces and some completion mechanics in general, let’s turn our attention to creating or producing implementations of those four async interfaces. As we’ve already learned, implementing WinRT interfaces with C++/WinRT is very simple. I might for example … Any Windows Runtime API that has the potential to take more than 50 milliseconds to complete is implemented as an asynchronous function (with a name ending in "Async"). The implementation of an asynchronous function initiates the work on another thread, and returns immediately with an object that … See more The code example below receives an asynchronous operation object from RetrieveFeedAsync, and it calls geton that object to block the calling thread until the results of the asynchronous operation are available. If you want … See more If you're asynchronously returning a type that's not a Windows Runtime type, then you should return a Parallel Patterns Library (PPL) concurrency::task. We recommend concurrency::task because it gives you better … See more C++/WinRT integrates C++ coroutines into the programming model to provide a natural way to cooperatively wait for a result. You can produce your own Windows Runtime … See more In this next example we wrap a call to RetrieveFeedAsync, for a specific URI, to give us a RetrieveBlogFeedAsync function that asynchronously … See more

With C++/WinRT, you can call Windows Runtime APIs using Standard C++ data types, including some C++ Standard Library data types.You can pass standard strings to APIs (see String handling in C++/WinRT), and you can pass initializer lists and standard containers to APIs that expect a semantically equivalent collection.. … WebJan 27, 2024 · The examples showing implementation of MIDI in winrt use the C# features await, async - are there any examples showing how methods like DeviceInformation.FindAllAsync(midiOutportQueryString) might be used in straight C++?
