How do I implement atomic operations in C?

How do I implement atomic operations in C?

To implement atomic operations in C, you can use the atomic built-in functions provided by the C11 standard.

Can you give me an example of using atomic variables?

Sure! You can use atomic_int to create an atomic integer. Here's a simple example:

#include <stdatomic.h>
#include <stdio.h>

int main() {
    atomic_int count = 0;
    atomic_fetch_add(&count, 1);
    printf("Count: %d\n", atomic_load(&count));
    return 0;
}

What are the benefits of using atomic operations?

Atomic operations help prevent data races in multi-threaded programs by ensuring that operations on shared variables are completed without interruption.

Are there any limitations to using atomic operations?

Yes, atomic operations can be limited in terms of the types they support and may not be as flexible as mutexes for complex data structures.
