std::chrono::duration<Rep,Period>::count: std::chrono::duration<Rep,Period>::count

NAME

std::chrono::duration<Rep,Period>::count - std::chrono::duration<Rep,Period>::count

Synopsis

constexpr rep count() const;

Returns the number of ticks for this duration.

Parameters

(none)

Return value

The number of ticks for this duration.

Example

// Run this code

  #include <chrono>
  #include <iostream>
  int main()
  {
      std::chrono::milliseconds ms{3}; // 3 milliseconds
      // 6000 microseconds constructed from 3 milliseconds
      std::chrono::microseconds us = 2*ms;
      // 30Hz clock using fractional ticks
      std::chrono::duration<double, std::ratio<1, 30>> hz30(3.5);

      std::cout << "3 ms duration has " << ms.count() << " ticks\n"
                << "6000 us duration has " << us.count() << " ticks\n"
                << "3.5 30Hz duration has " << hz30.count() << " ticks\n";
  }

Output:

  3 ms duration has 3 ticks
  6000 us duration has 6000 ticks
  3.5 30Hz duration has 3.5 ticks
