CURLOPT_STDERR(3) curl_easy_setopt options CURLOPT_STDERR(3)
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_VER-
BOSE(3) data.
If you are using libcurl as a win32 DLL, this option will cause an ex-
ception and crash in the library since it cannot access a FILE * passed
on from the application. A work-around is to instead use CURLOPT_DEBUG-
FUNCTION(3).
DEFAULT
stderr

EXAMPLE
CURL *curl = curl_easy_init();

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