1. Source code preparation This article is based on the analysis of the source code of gcc-4.9.0. std::function is added to the standard only after C++11. Therefore, the lower version of GCC source code does not have std::function. It is recommended to choose 4.9.0 or later version to learn. The difference between different versions of ...

For compile time type derivation, in addition to the auto keyword we mentioned, there is also decltype in this paper. Decltype, like the auto keywo ...

In this article, we will discuss how to stop or terminate threads in C++11.
