What happens after SDL_GetTicks() has reached sizeof(Uint32)?

Question

The return type of SDL's time function SDL_GetTicks() is Uint32 which is a typedef uint32_t Uint32. The function gives the milliseconds after the start of the SDL application.

Now, 32 bits of unsigned integer holding milliseconds are roughly 50 days. Assuming I write an application (e.g. a game server that runs 24/7) that uses this function to calculate run speed, what will happen after 50 days of runtime when the 32 bit unsigned integer is full?

Answer 1

It overflows.

According to this website and some other resources, the value will start over every 49.7 days.
