What are some examples of using stdatomic in C?

The stdatomic.h header in C provides atomic operations for multi-threaded programming. Would you like to see a specific example?

Yes, can you show me an example of atomic integer operations?

Sure! Here's a simple example:

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

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

This code initializes an atomic integer and increments it atomically.

What about using atomic flags?

For atomic flags, you can use atomic_flag like this:

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

int main() {
    atomic_flag lock = ATOMIC_FLAG_INIT;
    if (!atomic_flag_test_and_set(&lock)) {
        // Critical section
        printf("Lock acquired!\n");
        atomic_flag_clear(&lock);
    }
    return 0;
}

This code demonstrates how to use an atomic flag for locking.
