Fair enough, my apologies...I had read the tutorial, and some other misc
howtos. I had not read the man page for that function. I will be more
thorough next time.

How can I get vc++ to reference the line number in the curl source when
compiling my app? Is it as simple as compiling in the curl debug symbols
when building the lib?

Yep, every single time. At first I was thinking it was because it is an MFC
app and stdout might not be bound to anything (never tried to write to
stdout from an MFC app) so I tried setting up the write_data function as in
the tutorial as a static function within the class but the behavior did not
change at all.

sure...I will let you know if that does it as well. I might even be able to
assist in the debug if I can figure out how to make vc++ reference the
libcurl source during debug from within my project. Thanks,
