How can I debug multithreaded applications in C?

Debugging multithreaded applications can be challenging. You can use tools like GDB or Valgrind. Have you tried these?

I've used GDB, but I'm not sure how to set breakpoints for different threads.

In GDB, you can use the thread command to switch between threads. Set breakpoints in the context of the specific thread you want to debug.

What about race conditions? How can I identify them?

Race conditions can be tricky. Tools like ThreadSanitizer can help detect them. You can also review your code for shared resource access.

Are there any best practices to avoid race conditions?

Yes! Use mutexes for shared resources, avoid global variables, and consider using higher-level abstractions like thread pools.
