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

    curl_easy_setopt(curl, CURLOPT_STDERR, filep);


    curl_easy_perform(curl);


  }
}
