Cooperative Interruption of a Thread in C++20: CallbacksJuly 15, 2024 - 8:43 am
I introduced in my last post “Cooperative Interruption of a Thread in C++20” callbacks. Today, I dive deeper. First , here’s a short reminder. Reminder In my last post “Cooperative Interruption of a Thread in C++20“, I presented the following program. // invokeCallback.cpp #include <chrono> #include <iostream> #include <thread> #include <vector> using namespace::std::literals; auto func […]
Cooperative Interruption of a Thread in C++20July 1, 2024 - 10:12 am
A typical question in my C++ seminars is: Can a thread be killed? Before C++20, my answer is no. With C++20, you can ask a thread politely for its interruption.
Chrono: InputJune 24, 2024 - 9:36 am
You can also apply the format specifier for formatted input. This post is the eleventh in my detailed journey through the chrono extension in C++20. The chrono library supports formatted input in two ways. You can use the function std::chrono::from_stream or std::chrono::parse. Both functions require an input stream and parse the input into a time […]
