NAME¶

std::chrono::duration::count - std::chrono::duration::count

Synopsis¶

constexpr rep count() const; (since C++11)

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
