What are some effective tools for detecting deadlocks in C++?

There are several tools you can use to detect deadlocks in C++, such as Helgrind, ThreadSanitizer, and Visual Studio's Concurrency Visualizer.

Can you explain how Helgrind works?

Helgrind is a thread error detector that comes with Valgrind. It analyzes your program's execution to identify potential deadlocks by tracking lock acquisitions and releases.

Are there any built-in features in C++ for deadlock detection?

C++ itself doesn't have built-in deadlock detection, but you can implement your own mechanisms using smart pointers and lock management.

What are some best practices to avoid deadlocks in C++?

To avoid deadlocks, you can use lock hierarchies, avoid nested locks, and use timeouts when acquiring locks.
