How can I handle errors in a multi-threaded application using std::thread?

You can handle errors in a multi-threaded application by using try-catch blocks within each thread. This allows you to catch exceptions that occur in individual threads.

What if I want to propagate the error back to the main thread?

You can use a shared data structure, like a mutex-protected variable, to store the error information and check it in the main thread after joining the worker threads.

Can you give me an example of how to implement that?

Sure! You can create a vector of threads and a shared variable to hold the error. Each thread can update this variable if an error occurs, and the main thread can check it after joining.

What about using futures for error handling?

Using futures is a great approach! You can use std::async to run tasks asynchronously and handle exceptions by checking the future's status.
