Reader-Writer Locks
With C++14 came reader-writer locks. The idea is straightforward and promising. Arbitrary reading threads can access the critical region simultaneously, but only one thread is allowed to write.

I created a repository for the source code. It’s on GitHub and has the name ModernesCppSource:https://github.com/RainerGrimm/ModernesCppSource.git
Threads Sharing Data
One of the biggest challenges of thread management begins when the threads share non-const data
Thread Arguments
A thread gets its data by copy or by reference. By default, you should use by copy. Why? In case your thread gets its data by reference, you have to be extremely careful about the lifetime of the arguments.
Threads Lifetime
The parent has to take care of their child. This simple idea has big consequences for a thread lifetime. The following program starts a thread that displays its ID.
For the Proofreaders and the Curious People
After a lot of discussion with my proofreaders, we finally have a process to publish the articles.
Thread Creation
Thread creation is easy. Call std::thread, and a new thread will be created. The thread gets a work package and starts it immediately. The creator of the thread (the Parent) has to take care of the created thread (the child). The parent should wait until their child completes their task or has to detach himself […]
Multithreading in Modern C++
With the new C++11 Standard, C++ faces the first-time challenges of multicore architectures. The 2011 published standard defines how a C++ program has to behave in the presence of multiple threads. The C++11 multithreading capabilities are composed of two components. On the one hand, this is the defined memory model, and on the other hand, the […]
Why my Blog in English?
For half a year I have a blog about modern C++: Modernes C++. Although 80% of the readers are used to English, the blog is written in German. So I decided to translate the articles successively into English. Because my English is not as good as my German I asked a few people for help. They […]
Über mich
Beruflich Ich bin seit gut 15 Jahre Softwareentwickler. Da ich die permante Fortbildung als die entscheidende Eigenschaft für einen Softwareentwickler verstehe, habe ich bei meinem alten Arbeitgeber science&computing 2002 eine Fortbildungsrunde gegründet und bis zu meinem Wechsel zu Metrax 2013 am Leben gehalten. Durch die Koordination der Fortbildungsrunde veränderte sich auch deutlich mein Arbeitstag. Ich hielt sehr […]
