NAME

6       CURLOPT_STDERR - redirect stderr to another stream
7

SYNOPSIS

9       #include <curl/curl.h>
10
11       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_STDERR, FILE *stream);
12

DESCRIPTION

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.
17
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).

DEFAULT
