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
exception and crash in the library since it cannot access a FILE *
passed on from the application. A work-around is to instead use CUR-
LOPT_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
Always
RETURN VALUE
Returns CURLE_OK
