14 Pass a FILE * as parameter. Tell libcurl to use this stream instead of
15 stderr when showing the progress meter and displaying CURLOPT_VER‐
16 BOSE(3) data.

18 If you are using libcurl as a win32 DLL, this option will cause an ex‐
19 ception and crash in the library since it cannot access a FILE * passed
20 on from the application. A work-around is to instead use CURLOPT_DEBUG‐
21 FUNCTION(3).
