How do I use atomic operations in C?

How do I use atomic operations in C?

Atomic operations in C are used to perform operations on variables in a way that guarantees they are completed without interruption. You can use the <stdatomic.h> header for this.

Can you give me an example of an atomic operation?

Sure! Here's a simple example: using atomic_fetch_add to increment a variable atomically. You would declare your variable as atomic_int and then call atomic_fetch_add(&myVar, 1);.

What are the benefits of using atomic operations?

The main benefits include avoiding race conditions in multi-threaded environments and ensuring data integrity without using locks.

Are there any limitations to atomic operations?

Yes, atomic operations can only be applied to certain data types, and they may not be as flexible as using mutexes for complex operations.
