What are the different types of locks in C++?

In C++, there are several types of locks, including mutexes, recursive mutexes, shared mutexes, and timed mutexes. Would you like to know more about each type?

Yes, please explain mutexes and recursive mutexes.

A mutex (mutual exclusion) is a lock that prevents multiple threads from accessing a resource simultaneously. A recursive mutex allows the same thread to lock it multiple times without causing a deadlock.

What about shared mutexes?

A shared mutex allows multiple threads to read a resource simultaneously but only one thread to write to it at a time, ensuring data integrity.

Can you give an example of using a mutex in code?

Sure! Here's a simple example:

#include <mutex>
std::mutex mtx;
void threadFunction() {
    mtx.lock();
    // critical section
    mtx.unlock();
}
