Hands-On Tour of Embedded Linux System Calls In Qt | #QtWS22
While Qt offers tremendous functionality in performing system level tasks in the framework via C++, there are some tasks that are best performed via system calls. However, making system calls in the traditional manner for a Qt application is destructive, since it conflicts with the Qt main event loop. In this talk, we will take a peek behind the Qt main event loop, briefly understand how it works, and see how making system calls in the traditional fashion results in degraded performance. We will learn how we can correctly make system calls in a Qt application and see examples in a real-world application. Learn more about Qt: https://qt.io
