Free Atomic Functions
Explore the use of free atomic functions in C++, focusing on their compatibility with std::shared_ptr. Understand how atomic operations manage thread-safe reference counting and ensure resource destruction, as well as the importance of avoiding race conditions with shared pointers in concurrent environments.
We'll cover the following...
The functionality of the flag std::atomic_flag and the class template std::atomic can also be used with free functions. Because these functions use pointers instead of references, they are compatible with C. The atomic free functions are available for the types that you can use with the class template std::atomic.
There is one prominent exception to the rule: you can apply the atomic free functions to the smart pointer std::shared_ptr.
