The fetch_add function returned 0 and 1 as the previous values before increment. Likewise, the fetch_sub returned 2 and 1 as the previously stored values before the subtraction or decrement of the one. Conclusion We implemented the basic operations in “std:: atomic” in this article. We le...

The built-in atomic unit 265 handles predefined atomic operators such as fetch-and-increment or compare-and-swap. In an example, these operations perform a simple read-modify-write operation to a single memory location of 32-bytes or less in size. Atomic memory operations are initiated from a...
