std::chrono..._point::min(3) C++ Standard Libary std::chrono..._point::min(3) NAME std::chrono::time_point::min - std::chrono::time_point::min Synopsis static constexpr time_point min(); (until C++20) static constexpr time_point min() noexcept; (since C++20) Returns a time_point with the smallest possible duration, i.e. time_point(std::chrono::duration::min()). Parameters (none) Return value The smallest possible time_point. Example // Run this code #include <chrono> #include <iomanip> #include <iostream> #include <ratio> #include <string> constexpr auto steady_min = std::chrono::steady_clock::time_point::min(); void animate_frame_at_time_offset(double game_time) { std::cout << std::string(static_cast<int>(game_time) % 10 + 1, '*') << '\n'; } int main() { auto last_frame = steady_min; std::chrono::duration<double, std::micro> game_time{0.0}; for (int n = 0; n < 5; ++n) { const auto current_frame = std::chrono::steady_clock::now(); // initialize timer if first frame ever: if (last_frame == steady_min) last_frame = current_frame; game_time += current_frame - last_frame; std::cout << "Drawing frame at " << std::setprecision(10) << std::setw(8) << game_time.count() << " I1/4s "; animate_frame_at_time_offset(game_time.count()); } } Possible output: Drawing frame at 0 I1/4s * Drawing frame at 134.499 I1/4s ***** Drawing frame at 274.337 I1/4s ***** Drawing frame at 416.571 I1/4s ******* Drawing frame at 561.124 I1/4s ** http://cppreference.com 2024.06.10 std::chrono..._point::min(3)
