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 win32 DLL, this option will cause an exception and 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

       CURL *curl = curl_easy_init();
       FILE *filep = fopen("dump", "wb");
       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
         curl_easy_setopt(curl, CURLOPT_STDERR, filep);

         curl_easy_perform(curl);
       }

AVAILABILITY
