How does STM32F0 core handle unsigned long int overflow

For example, if I have:

unsigned long int Variable1;

Variable1 = 0xFFFFFFFF;

Variable1++;

What would be the value of Variable1? Would it be back to zero?

Thanks.

Well I need a long time elapsed.  For example, if I need to keep track of time longer than 30 seconds, does uwTick able to support that?

Yes, if ticking at 1ms the wrap time is a little over 49 days.

Ticking at 72 MHz, around a minute.
