I previously practiced handwriting a small thread pool version (uploaded to Https://github.com/xhjcehust/thread-pool), reviewed in recent days, found that most thread pool implementations are inseparable from the use of locks, such as mutex

Understanding the parsing process of a function is critical to understanding the inheritance of C + +, assuming we call P->mem (), perform the following four steps in turn:1. First determine the static type of P. Because we are invoking a member,
