How can I fix data race bugs in my application?

How can I fix data race bugs in my application?

Data race bugs occur when two or more threads access shared data simultaneously. To fix them, you can use synchronization techniques like mutexes or semaphores.

What are mutexes and how do I use them?

Mutexes, or mutual exclusions, are used to prevent multiple threads from accessing shared resources at the same time. You can implement a mutex by locking it before accessing the shared resource and unlocking it afterward.

Are there any tools to help detect data races?

Yes, there are several tools like ThreadSanitizer, Helgrind, and Intel Inspector that can help you detect data races in your code.

Can you give me an example of using a mutex in code?

Sure! Here's a simple example in C++:

#include <mutex>
std::mutex mtx;

void safeIncrement(int &counter) {
    mtx.lock();
    counter++;
    mtx.unlock();
}
