Quoting the first line again from cpp reference: the class jthread represents a single thread of execution … , and can be cancelled/stopped…Cpp7 min read
PinnedC++ 20 Concepts: part 1 (the basics)Concepts is one of the 4 major additions in C++20 standard. The idea of concepts has existed as long as C++ templates themselves but it has only been until few years that the foundation of C++ concepts have been laid out in the manner it had earlier been desired desired…Cpp 205 min read

May 2C++20 Coroutines back to basics — Restrictions and rules for legal coroutines1. Introduction In my previous articles on coroutines, I attempted to explain the mechanics of coroutine suspension, resuming it, promise_type, awaiters and awaitables. In this article, I would like to answer two very basic questions: What are the restrictions on coroutines ? When can a coroutine usage be legal in terms of…Cplusplus5 min read
Jan 10C++20 Concurrency — Part 2: jthreadsIn this part of the issue, I’ll discuss about the new std::jthread that helps us avoid the boilerplate code for joining the conventional std::thread in the first section. In the end, I’ll also mention about the std::swap algorithm’s specialization introduced in C++20 to swap the underlying thread handles associated with…Cpp3 min read
Jan 5C++ 20 concurrency Part 1: synchronized output streamMost of C++ developers who have been using concurrency features are well aware of the problems of std::ostream or std::cout with multi threading. The outputs are almost all the time undeterministic and worse they are always entangled with each other in ways which makes std::cout unusable in concurrent applications. The Problem Consider…Cpp4 min read
