Need VS2008 Verification

OK, I've been banging my head over what appears to be some weird behavior in the CRT under VS2008 (debug mode). Here's the code:

Code:

const time_t timeStamp = 1223939307;
char qs[256] = { 0 };
int actualLen = sprintf_s(qs, sizeof(qs), "%lu----%s---", timeStamp, "rukiddingme?");

Yields (in the debugger):

Code:

qs = 0x0012e998 "1223939307----(null)---"

It seems if I put that timestamp in an _snprintf, sprintf, or sprintf_s, the string which follows ends up (null) in the resulting string.

Can anyone verify this? Have I lost the ability to use sprintf over the weekend? It really was totally not wild, although I was dealing with Vista at one point...

Thanks!

Is sizeof(time_t)==sizeof(long)?

Nope, it's actually unsigned int (damn my Linux-based expectations), but sadly, changing the format specifier to %u did not change the behavior.

sizeof(%lu) == 4 (sizeof(%u) is also 4)
sizeof(time_t) == 8
Can you spot the error?

Dammit, what the hell was I thinking...in my haste I read the sizeof output incorrectly in the debugger...

And hence, how I achieved my hat of Ass.

Thanks, Elysia!

No problem.

"You made me look quite the fool, thanks Elysia!!!!"

Man I hope that makes it to her sig.

I don't want to add something insulting to the signature.
Without proper permission and desire from the original poster. And of course, it could be removed at any time. But I don't think it's necessary.
