C++11 allows the use of atomics in signal handlers. In C++17 the signal handler feature is further improved. The std::atomic_flag is an atomic boolean type that is guaranteed to be lock-free and can be used in signal handlers. Moreover, the <csignal> header in C++ has an integer type std::sig_atomic_t that can be accessed as an atomic entity even in the presence of asynchronous…
Modern C++ has many features to aid multi-thread programming that allow applications to be faster and more responsive. The C++11 standard offers the possibility of moving an exception from one thread to another. This type of movement is called propagating exceptions…
C++ is very strong in every aspect of modern programming. Volatile types are used with the volatile keyword. It is a lesser known type qualifier that is important to read types or objects whose value can be modified at any time. The volatile keyword is useful in…
Since the C++11 standard, the Concurrency Support Library includes built-in support for threads (std::thread) with atomic operations (std::atomic). C++11 provides both weak and strong compare-and-exchange operations in multi-threading applications. Since C++11, weak compare and exchange are used in modern C++ standards such as C++14, C++17, C++20, and in other new standards. In this post, we…

Inmulti-thread programming, data races are a common problem in threads. Data races occur when multiple tasks or threads access a shared resource without sufficient protection, leading to undefined or unpredictable behavior on runtime. In C++, the concurrency support…
What Is A Data Race In Multi-threading C++ Apps And How To Avoid It
September 1, 2023
In modern programming, if you are developing multithreaded applications, data races are a common problem in threads. Data races occur when multiple tasks or threads access a shared resource without sufficient protection, leading to undefined or unpredictable behavior on runtime. You can imagine two or more task threads in cores trying to reach the same data in a race. In this post, we explain…
Learn Useful Bidirectional Fences In Modern Multi-threading C++ Apps
September 1, 2023
C++11 improved the support for bidirectional fences in multi-thread applications. In modernC++ development,Fencesare synchronization primitives in multi-threading operations, they are memory barriers in threads, and they can acquire semantics, release…
Using multi-threading development skills on the CPU, GPU, and memory operations is important in programming, but it can give rise to problems in synchronization of multi-thread operations and reaching data for reading and writing. The concurrency support library in modern…
The concurrency support library in modern C++ is designed to solve problems in multi-thread operations. Since the C++11 standard, this library includes built-in support for threads (std::thread) with atomic operations (std::atomic). In this post, we explain two atomic operations that can be used with std::atomic types, we explain what are atomic addition and subtraction operations.
What is…
