Creating a task completion source for a C++ coroutine: Failing to produce a result

by Raymond Chen

From the article:

So far, we’ve been working on building a result_holder that can hold any type of result. But what about errors?

Because maybe you have code that’s waiting for a result, and the code that’s supposed to produce the result realizes that it messed up and wants to say, “Sorry, no result today.”...

Cling -- Beyond Just Interpreting C++

by Vassil Vassilev, Wim Lavrijsen, Alexandru Militaru

From the article:

In our previous blog post “Interactive C++ for Data Science” we described eval-style programming, interactive C++ in Notebooks and CUDA. This post will discuss some developed applications of Cling supporting interoperability and extensibility. We aim to demonstrate template instantiation on demand; embedding Cling as a service; and showcase an extension enabling on-the-fly automatic differentiation...

Italian C++ Conference 2021 - Call for Sessions

by Marco Arena

From the article:

Since 2016, the Italian C++ Conference is the biggest and most successful event organized by the Italian C++ Community where professionals, companies and students meet to share experience about C++ development and practices.

The next conference is planned for June 19, online (Remo) and will be free to attend (as usual)...

Creating a task completion source for a C++ coroutine: Producing a result

by Raymond Chen

From the article:

We’ve been looking at creating different types of awaitable synchronization objects. This time, we’ll create something analogous to what C# calls a Task­Completion­Source and what PPL calls a task_completion_event. For lack of a better name, I’m going to call it a result_holder...

Ticket Maps

by Anthony Williams

From the article:

It has been an increasingly common scenario that I've encountered where you have some ID that's monotonically increasing, such as a subscription or connection index, or user ID, and you need your C++ program to hold some data that's associated with that ID value. The program can then pass round the ID, and use that ID to access the associated data at a later point...

Creating other types of synchronization objects that can be used with co_await, part 10

by Raymond Chen

From the article:

We’ve been looking at creating different types of awaitable synchronization objects. This time, we’re going to create something that doesn’t exist in the normal Win32 repertoire: An event where you can wait for the event to be in a desired state, either set or reset. Normal Win32 events allow you to wait for them to be set, but you cannot wait for Win32 event to be reset. The usual workaround is to have two events...
