What are the new features in C++20 related to exceptions?
An example of an AI chatbot conversation about C++20's standard exception handling features.
What are the new features in C++20 related to exceptions?
C++20 introduced several enhancements to exception handling, including the new 'std::exception_ptr' and 'std::terminate_handler'.
Can you explain how 'std::exception_ptr' works?
Sure! 'std::exception_ptr' is a smart pointer that can hold a pointer to an exception object, allowing you to rethrow exceptions across different threads.
What about 'std::terminate_handler'? How is it different?
'std::terminate_handler' allows you to set a custom handler that will be called when an exception is thrown and not caught, providing more control over program termination.
Are there any changes to the way exceptions are thrown in C++20?
Yes, C++20 allows for the use of 'noexcept' specifications to indicate whether a function can throw exceptions, improving performance and safety.
