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...

Simple and efficient.

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...
