std::chrono...ration::zero(3) C++ Standard Libarystd::chrono...ration::zero(3) NAME std::chrono::duration::zero - std::chrono::duration::zero Synopsis static constexpr duration zero(); (until C++20) static constexpr duration zero() noexcept; (since C++20) Returns a zero-length duration. If the representation rep of the duration requires some other imple- mentation to return a zero-length duration, std::chrono::duration_values can be specialized to return the desired value. Parameters (none) Return value Returns duration(std::chrono::duration_values<rep>::zero()). Example // Run this code #include <chrono> #include <ratio> template<typename X, typename Y> using dura = std::chrono::duration<X, Y>; static_assert ( (std::chrono::hours::zero() == std::chrono::nanoseconds::zero()) && (dura<short, std::nano>::zero() == dura<int, std::deci>::zero()) && (dura<short, std::deca>::zero() == dura<long, std::exa>::zero()) && (dura<long, std::atto>::zero().count() == dura<float, std::exa>::zero().count()) ); int main() {} See also min returns the special duration value min [static] (public static member function) max returns the special duration value max [static] (public static member function) http://cppreference.com 2024.06.10 std::chrono...ration::zero(3)
