could you send a full example (compilable)?

Thanks,

Hi Patrick,

Thanks for the tip, but sadly it still doesn't work for me. When I use a
reference (&) all the verbose info gets displayed to the console, while
with a pointer (*) it  vanishes (not on the console or in the file).
Do you think anything else could be causing this problem?

Thanks for the assistance,
Chris

Hi,

try passing a FILE * to the curl_easy_setopt instead of a FILE &.

Best Regards

Issue with Outputting CURL Verbose Info to a File

[Chris Molnar]

 Hi All,

I seem to be running into a problem when trying to output the verbose info
to a file. I have set it up to send using curl_easy_setopt(curl, CURLOPT,
file) as it shows on the website (the first 2 links below) but it never
seems to output anything to the file. I looked further into this problem
and found that someone had the same problem but the suggested solution only
seemed to work on Linux and not Windows (as seen in the 3rd link). I was
wondering if anyone had any knowledge of this being a problem on Windows
devices or a possible work around? I have attached a snippet of my code
below.

Thank you for your time and help
