- std::mutex - cppreference. com
The mutex class is a synchronization primitive that can be used to protect shared data from being simultaneously accessed by multiple threads mutex offers exclusive, non-recursive ownership semantics: A calling thread owns a mutex from the time that it successfully calls either lock or try_lock until it calls unlock

- Can someone Explain Mutex and how it is used? - Stack Overflow
A mutex provides mut ually ex clusive access to a resource; in your case, a database There aren't multiple threads in your program, but you can have multiple instances of your program running, which is what your mutex is protecting against
- std::recursive_mutex - cppreference. com
The recursive_mutex class is a synchronization primitive that can be used to protect shared data from being simultaneously accessed by multiple threads recursive_mutex offers exclusive, recursive ownership semantics: A calling thread owns a recursive_mutex for a period of time that starts when it successfully calls either lock or try_lock
- What is the difference between lock, mutex and semaphore?
I've heard these words related to concurrent programming, but what's the difference between lock, mutex and semaphore?
- c++ - How do mutexes really work? - Stack Overflow
However, how is this implemented? To lock itself, the mutex has to set a bit somewhere that says that it is locked But what if the second mutex is reading at the same time the first is writing Worse, what if they both lock the mutex at the same time? The mutex would succumb to the same problem it is meant to prevent How do mutexes really work?
