What is stdatomic and how does it work in multithreading?

Can you explain what stdatomic is and its role in multithreading?

Sure! stdatomic is a C11 feature that provides atomic operations for multithreading, ensuring safe access to shared variables.

How does stdatomic help prevent data races?

It provides atomic types and operations that guarantee that reads and writes to shared variables are done without interference.

Can you give an example of using stdatomic in a multithreaded program?

Certainly! For instance, you can use stdatomic to increment a shared counter safely across multiple threads using atomic_fetch_add.

Are there any performance considerations when using stdatomic?

Yes, while stdatomic ensures safety, it may introduce some overhead compared to non-atomic operations, so it's important to use it judiciously.
