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

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
       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
