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

There are several tools you can use to detect deadlocks in C++, such as Valgrind, Helgrind, and ThreadSanitizer. These tools help identify synchronization issues in multithreaded applications.

How does Valgrind help in detecting deadlocks?

Valgrind provides a framework for memory debugging and profiling. It can detect deadlocks by analyzing the program's thread interactions and reporting any potential deadlock situations.

Are there any specific features in ThreadSanitizer for deadlock detection?

Yes, ThreadSanitizer can detect data races and potential deadlocks by monitoring thread interactions and reporting when threads are waiting indefinitely for resources.

Can you give me an example of a deadlock scenario in C++?

Sure! A common deadlock scenario occurs when two threads each hold a lock and wait for the other to release their lock, causing both to be stuck indefinitely.
