sdlGetTicks64 function
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.
