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

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); }
