NAME

       CURLOPT_STDERR - redirect stderr to another stream

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_STDERR, FILE *stream);

DESCRIPTION

       Pass  a  FILE * as parameter. Tell libcurl to use this stream instead of stderr when showing the progress
       meter and displaying CURLOPT_VERBOSE(3) data.

       If you are using libcurl as a Windows DLL, this option causes an exception and a  crash  in  the  library
       since  it  cannot  access  a  FILE  *  passed  on  from  the application. A work-around is to instead use
       CURLOPT_DEBUGFUNCTION(3).

DEFAULT

       stderr

PROTOCOLS

       All

EXAMPLE

       int main(void)
       {

         if(curl) {
           curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
           curl_easy_setopt(curl, CURLOPT_STDERR, filep);

           curl_easy_perform(curl);
         }
       }
