SDL_GetTicks() accuracy below the millisecond level

Question

I program currently something with SDL2. All works fine, but I have a problem with the SDL_GetTicks() method. Normally it should return the total application ti

You cannot use SDL_GetTicks() if you want higher precision but there are many other alternatives. If you want to be platform independant you need to be careful though, but here is a portable C++11 example that will get you started:

#include 
#include 
typedef std::chrono::high_resolution_clock Clock;

int main()
{
    auto t1 = Clock::now();
    auto t2 = Clock::now();
    std::cout << "Delta t2-t1: " 
              << std::chrono::duration_cast(t2 - t1).count()
              << " nanoseconds" << std::endl;
}

Running this on ideone.com gave me:

Delta t2-t1: 282 nanoseconds
