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

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

Thread safety in C++11 std::map refers to the ability to safely access and modify the map from multiple threads without causing data races or inconsistencies.

How can I ensure that my std::map is thread-safe?

You can ensure thread safety by using mutexes to lock the map during read and write operations, or by using concurrent data structures.

Are there any specific functions in std::map that are not thread-safe?

Yes, most operations like insert, erase, and find are not thread-safe when accessed concurrently. You need to manage access with synchronization.

What are some alternatives to std::map for thread-safe operations?

Alternatives include concurrent data structures like concurrent_hash_map from Intel's Threading Building Blocks or using std::unordered_map with proper locking.
