About logprintf syntax: I am not sure if I understand it correctly:

logprintf("\n[nTotalImages %d nGoodImages %d "
"Mean times: FaceDet %.3f AsmSearch %.3f Both %.3f secs]\n",
nTotalImages, nGoodImages,
TotalDetTime / nGoodImages, TotalAsmTime / nGoodImages,
MeanTime);

My ideas:
\n stands for "new line", yes?
..3f stands for a a number with 3 decimal places, yes?
and the % which occurs 5 times in the sample above stands for 5
variables which can be found in the second argument of logprintf, yes?

About logprintf syntax

Anna,

What's logprintf - something of your own making?

Assuming it's a wrapper you have for some printf formatting...
\n stands for "new line", yes?
Yes.

.3f stands for a a number with 3 decimal places, yes?

a precision of .3 with type f (floating point value) means 3 decimal
places.
and the % which occurs 5 times in the sample above stands for 5
variables which can be found in the second argument of logprintf, yes?
Click to expand...

Yes.

You can find an explanation for all these points in the MSDN article
"Format Specification Fields: printf and wprintf Functions"
