How can I handle errors in C++ thread library?

How can I handle errors in C++ thread library?

In C++, you can handle errors in the thread library by using exceptions. For example, you can catch exceptions thrown by thread operations.

Can you give me an example of error handling with threads?

Sure! Here's a simple example:

#include <iostream>
#include <thread>
#include <stdexcept>

void threadFunction() {
    throw std::runtime_error("Error in thread");
}

int main() {
    try {
        std::thread t(threadFunction);
        t.join();
    } catch (const std::exception& e) {
        std::cerr << "Caught exception: " << e.what() << std::endl;
    }
    return 0;
}

What happens if I don't handle exceptions in threads?

If you don't handle exceptions in threads, the program may terminate unexpectedly, and you might lose important data or state.

Are there any best practices for error handling in C++ threads?

Yes, some best practices include always joining threads, using try-catch blocks, and logging errors for debugging.
