How do I use stdatomic.h in C for atomic operations?

You can use stdatomic.h to perform atomic operations in C, which helps in writing thread-safe code. What specific operations are you interested in?

I want to know how to perform atomic increment and decrement.

You can use atomic_fetch_add and atomic_fetch_sub functions for incrementing and decrementing. Would you like a code example?

Yes, please provide a code example.

Here's a simple example:

#include <stdatomic.h>

int main() {
    atomic_int counter = 0;
    atomic_fetch_add(&counter, 1); // Increment
    atomic_fetch_sub(&counter, 1); // Decrement
    return 0;
}

This code initializes an atomic integer and performs increment and decrement operations.

What are the benefits of using atomic operations?

Atomic operations prevent data races and ensure that operations on shared variables are completed without interruption.
