What is thread safety in C++11 std::list?

Can you explain what thread safety means in the context of C++11 std::list?

Thread safety refers to the property of a data structure that ensures safe access by multiple threads. In C++11, std::list is not inherently thread-safe, meaning concurrent modifications can lead to undefined behavior.

What happens if two threads try to modify a std::list at the same time?

If two threads modify a std::list simultaneously without proper synchronization, it can result in data corruption, crashes, or unexpected behavior due to race conditions.

How can I make std::list thread-safe?

You can make std::list thread-safe by using synchronization mechanisms like mutexes or locks to control access to the list during modifications.

Are there any alternatives to std::list that are thread-safe?

Yes, you can consider using concurrent data structures from libraries like Intel TBB or concurrent queues that are designed for thread safety.
