You don't have the right stdout.
Take another look at my code.

This doesn't look right.
It looks like you are copying the FILE structure.
 I would think
	stdout = pfile;

Not sure why you need setvbuf.
I also find it unsettling that "*stdout=" would affect cout.
Also, if the previous "copy FILE" is an error, then quite likely it
would cause your "The handle is invalid." problem at this point.
