Creating a task completion source for a C++ coroutine: Producing a result with references
by Raymond Chen
From the article:
Last time, we created a result_holder that can be awaited until it is assigned a result, and I noted that the code was broken.
One of the reasons that it’s broken is that it doesn’t handle references properly...

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...

Constexpr all the things.
constexpr Dynamic Memory Allocation, C++20
by Bartlomiej Filipek
From the article:
constexpr has become a major feature for compile-time programming in C++. Introduced in a simple form in C++11 evolved into almost another “sub-language”, an alternative to regular template code. In C++20 you can even use std::vector and std::string in constexpr context!
In this article, I’d like to discuss constexpr memory allocations, a building block for std::vector. Let’s see how this feature works and see its limitations...

Call for Sessions
by Marco Arena
About the conference:
The Italian C++ Conference 2021 will be online on June 19 and will host live sessions and networking on Remo.
The Italian C++ Conference is the biggest and most successful event organized by the Italian C++ Community and it is an environment where professionals, companies and students meet to share experience about C++ development and practices.
Since the first edition back in 2016, the conference has hosted amazing speakers like Andrei Alexandrescu, Walter Brown, Michael Wong, James McNellis, Bartosz Milewski, Ivan Čukić, Jens Weller, Phil Nash, Anastasia Kazakova, Peter Sommerlad, Rainer Grimm, Marc Goodner, Vittorio Romeo, and many more.
The Italian C++ Conference is put on by the Italian C++ Community and is open to anyone who wishes to be there either as a presenter or an attender.
The event will be free to attend.
The Call for Sessions will close on April 11 at 23:59 CET.

Creating other types of synchronization objects that can be used with co_await, part 8

From the article:
Our next stop in showing off our library for building awaitable synchronization objects is the shared mutex. This one takes advantage of the “extra data” we had been hiding in our nodes...
