Could someone tell me how to printf the long long int's (64 bit). I've looked for the docs on it and maybe I've missed it.

I've got a utility I am writing where I need to report on files larger than 4 Gig and some of the numbers I am keeping track of can easily exceed unsigned longs.

Thanks!

To print long long (64-bit integer) use %lld or %llu.
But since you posted this in DOS thread, I doubt that you can have files
larger than 2Gb in DOS. Can you?

Also, the 64 bit long long type is not implemented for 16 bit models; just 32 bit models.

You're quite correct.  I posted to the wrong group.

Thanks to those replying for all for the info though.

I am using Windows Console mode for the utility.

Since I am here....  I did notice that those long long's hog the processor (and probably the general machine architecture) a whole lot more than I was hoping for.

The program execution speed dropped quite noticeably from just using unsigned longs.

I am not so up on the processor architecture as I should be at the moment. Don't the Pentium III's have 64 bit wide registers anywhere in their construction that the compiler is able to use for register variables?  I know it is basically a 32 bit device, but can't some registers can be "grouped" where they would be used and act as 64 bit registers instead of 2 - 32 bit registers?

The performance hit was enough to consider two versions of the utility.

Thanks again, and Walter, YOU'RE THE MAN.  I can't tell you how happy I was to see that this product is still going forward.  I first came across it as Symantec C++ version 7.5 and I loved the ease of use and overall speed(s) and configurability of the product.

No, not that I've found <g>.

Thanks!
