SDL_GetTicks

Get the number of milliseconds since SDL library initialization.

Syntax

Uint32 SDL_GetTicks(void);

Return Value

Returns an unsigned 32-bit value representing the number of milliseconds since the SDL library initialized.

Remarks

This value wraps if the program runs for more than ~49 days.

This function is not recommended as of SDL 2.0.18; use SDL_GetTicks64() instead, where the value doesn't wrap every ~49 days. There are places in SDL where we provide a 32-bit timestamp that can not change without breaking binary compatibility, though, so this function isn't officially deprecated.

Version

This function is available since SDL 3.0.0.

Code Examples

unsigned int lastTime = 0, currentTime;
while (!quit) {
  // do stuff
  // ...

  // Print a report once per second
  currentTime = SDL_GetTicks();
  if (currentTime > lastTime + 1000) {
    printf("Report: %d\n", variable);
    lastTime = currentTime;
  }
}
