# NAME
|
|
|
|
CURLOPT_STDERR - redirect stderr to another stream
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#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).
