Function sdl2_sys::SDL_GetTicks64

pub unsafe extern "C" fn SDL_GetTicks64() -> Uint64

Get the number of milliseconds since SDL library initialization.

Note that you should not use the SDL_TICKS_PASSED macro with values returned by this function, as that macro does clever math to compensate for the 32-bit overflow every ~49 days that SDL_GetTicks() suffers from. 64-bit values from this function can be safely compared directly.

For example, if you want to wait 100 ms, you could do this:

const Uint64 timeout = SDL_GetTicks64() + 100;
while (SDL_GetTicks64() < timeout) {
    // ... do work until timeout has elapsed
}

\returns an unsigned 64-bit value representing the number of milliseconds since the SDL library initialized.

\since This function is available since SDL 2.0.18.
