Webstatic data + static functions != singleton pattern. Static class (a class that contains only static data and functions) and singleton pattern are not same. In some cases it may seem same, but with static classes there are some problems e.g. You can not extend its functionality by inheritance since static functions can not be virtual. WebBefore C++11, doing that was not an easy job, and a double-checked locking technique was the typical approach. However, Scott Meyers and Andrei Alexandrescu showed, in a paper called C++ and the Perils of Double-Checked Locking , that using this pattern did not guarantee a thread-safe singleton implementation in portable C++.
