.TH CURLOPT_STDERR 3 "17 Jun 2014" libcurl libcurl
|
||
|
|
.SH NAME
|
||
|
|
CURLOPT_STDERR \- redirect stderr to another stream
|
||
|
|
.SH SYNOPSIS
|
||
|
|
.nf
|
||
|
|
#include <curl/curl.h>
|
||
|
|
|
||
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_STDERR, FILE *stream);
|
||
|
|
.fi
|
||
|
|
.SH DESCRIPTION
|
||
|
|
Pass a FILE * as parameter. Tell libcurl to use this \fIstream\fP instead of
|
||
|
|
stderr when showing the progress meter and displaying \fICURLOPT_VERBOSE(3)\fP
|
||
|
|
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 \fICURLOPT_DEBUGFUNCTION(3)\fP.
|
||
|
|
.SH DEFAULT
|
||
|
|
stderr
