The std::atomic::fetch_sub function in C++ is used to atomically subtract a specified value from the atomic object's value and fetches the result. This function ensures that the operation is performed in a thread-safe manner, preventing any potential race conditions that may arise when multiple threads try to modify the same value simultaneously. The function returns the value stored in the atomic object before the subtraction operation was performed.
