What are the differences between stdatomic locks and mutexes?
stdatomic locks are designed for low-level atomic operations, while mutexes are higher-level synchronization primitives. Mutexes can block threads, whereas stdatomic operations are non-blocking.
When should I use stdatomic instead of mutexes?
Use stdatomic when you need fine-grained control over shared data without the overhead of locking. It's ideal for performance-critical sections.
Are there any downsides to using stdatomic?
Yes, stdatomic can be more complex to implement correctly and may lead to subtle bugs if not used carefully. Mutexes are generally easier to use.
Can you give an example of stdatomic in action?
Sure! Here's a simple example: using std::atomic<int>
to safely increment a counter across multiple threads without locks.
