What are deadlocks in C++ and how can I avoid them?
Deadlocks occur when two or more threads are blocked forever, each waiting for the other to release a resource. To avoid them, you can use techniques like resource ordering, timeouts, or deadlock detection algorithms.
Can you give me an example of a deadlock situation?
Sure! Imagine two threads: Thread A holds Resource 1 and waits for Resource 2, while Thread B holds Resource 2 and waits for Resource 1. This creates a deadlock.
How can I implement resource ordering to prevent deadlocks?
You can assign a global order to resources and ensure that all threads acquire resources in that order. This way, circular wait conditions are avoided.
Are there any tools to help detect deadlocks in my C++ code?
Yes, tools like Valgrind and ThreadSanitizer can help detect deadlocks by analyzing your code during execution.
