What are common mistakes when using mutex in C++?

What are common mistakes when using mutex in C++?

Some common mistakes include forgetting to lock a mutex before accessing shared resources, leading to data races.

Can you explain what a data race is?

A data race occurs when two or more threads access shared data simultaneously, and at least one thread modifies it.

How can I avoid data races in my C++ code?

You can avoid data races by ensuring that all accesses to shared data are protected by mutex locks.

Are there any performance implications of using mutex?

Yes, excessive locking can lead to performance bottlenecks, so it's important to minimize the time a mutex is held.
