Can you provide advanced examples of using the standard thread library?

Can you provide advanced examples of using the standard thread library?

Sure! One advanced example is using thread pools to manage multiple threads efficiently. This allows you to limit the number of concurrent threads and reuse them for different tasks.

How do I implement a thread pool in C++?

You can implement a thread pool in C++ using the std::thread and std::mutex classes. Start by creating a class that manages a collection of threads and a queue of tasks.

What about handling exceptions in threads?

You can handle exceptions in threads by using try-catch blocks within the thread function. Make sure to propagate the exception back to the main thread if needed.

Can you show me a code snippet for that?

Certainly! Here's a simple example:

#include <iostream>
#include <thread>
#include <vector>
#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::cout << "Caught exception: " << e.what() << std::endl;
    }
}

This will catch the exception thrown in the thread.
