need to call a function at periodic time intervals in c++
c++, timer, visual-c++
Solution
To complete the question, the code from @user534498 can be easily adapted to have the periodic tick interval. It's just needed to determinate the next start time point at the beginning of the timer thread loop and `sleep_until` that time point after executing the function.
#include <iostream>
#include <chrono>
#include <thread>
#include <functional>
void timer_start(std::function<void(void)> func, unsigned int interval)
{
std::thread([func, interval]()
{
while (true)
{
auto x = std::chrono::steady_clock::now() + std::chrono::milliseconds(interval);
func();
std::this_thread::sleep_until(x);
}
}).detach();
}
void do_something()
{
std::cout << "I am doing something" << std::endl;
}
int main()
{
timer_start(do_something, 1000);
while (true)
;
}
Problem
I am writing a program in c++ where I need to call a function at periodic time intervals, say every 10ms or so. I've never done anything related to time or clocks in c++, is this a quick and easy problem or one of those where there is no neat solution? Thanks!
