What are the best practices for using semaphores in C++?
When using semaphores in C++, it's important to ensure proper initialization, avoid deadlocks, and use RAII for resource management.
Can you explain what RAII means in this context?
RAII stands for Resource Acquisition Is Initialization. It ensures that resources are properly released when they go out of scope, preventing leaks.
What are some common pitfalls to avoid with semaphores?
Common pitfalls include forgetting to release the semaphore, using it in a non-thread-safe manner, and not handling exceptions properly.
How do semaphores compare to mutexes?
Semaphores allow multiple threads to access a resource up to a limit, while mutexes provide exclusive access to a resource.
