GetTickCount return value

Sat, 15 Sep 2007 10:28:20 Z

Hi,

This might sound like a fundamental question, but after the system is up for more than 49.7 days and GetTickCount() returns 4294967296 which is wrapped around to 0, what does it return subsequently? Does it keep returning 4294967296 (wrapped around value 0) or does it return 4294967291, 4294967292, 4294967293 (wrapped around values 1, 2, 3) and so on.

TIA,

Vidya.

It will roll over to 0, and then start counting upwards again: 4294967295, 0, 1, 2, ...

Means GetTickCount() fails if the value greater than 2^32 i.e 4294967296????

Incidentally, Windows Server 2008 features GetTickCount64, which won't roll over to zero for quite a while.
