How can I debug multithreaded C++ applications effectively?

How can I debug multithreaded C++ applications effectively?

Debugging multithreaded applications can be challenging due to race conditions and deadlocks. You can use tools like GDB or Valgrind, and techniques like logging and breakpoints to help identify issues.

What specific tools do you recommend for detecting race conditions?

I recommend using ThreadSanitizer, which is part of Clang and GCC, as it can help detect data races in your code.

Are there any best practices to follow while writing multithreaded code?

Yes, some best practices include minimizing shared data, using mutexes wisely, and avoiding global variables to reduce complexity.

How can I test my multithreaded code to ensure it's working correctly?

You can use unit tests with frameworks like Google Test, and also perform stress testing to simulate high-load scenarios.
