What is exception safety in C++ threads?

What is exception safety in C++ threads?

Exception safety in C++ threads refers to the guarantees that a program will maintain a certain state even when exceptions occur during thread execution.

Can you explain the different levels of exception safety?

Sure! The three main levels are: no-throw guarantee, strong guarantee, and basic guarantee. Each level provides different assurances about resource management during exceptions.

What happens if a thread throws an exception?

If a thread throws an exception and it's not caught, it can lead to program termination. Proper exception handling is crucial to avoid this.

How can I ensure my C++ code is exception safe?

You can ensure exception safety by using RAII (Resource Acquisition Is Initialization), smart pointers, and writing exception-safe functions.

Are there any best practices for handling exceptions in multi-threaded applications?

Yes, best practices include using try-catch blocks, ensuring thread synchronization, and avoiding shared mutable state to minimize exceptions.
