Summary: A program for accessing https pages runs on Linux

Initial Comment:
but crashes on Windows. Because I'm very new to it, it
might be me misusing the library.
The point is I can access the page with either curl on
Windows or Linux but can not access the page with
libcurl under Windows.

- I have made my own server certificate and my own
personal certificat for accessing the pages.

Here's the code:
#include <stdio.h>
#include <curl/curl.h>

static int fetch_page (CURL *curl){
        CURLcode res;
        char err_buf [2* CURL_ERROR_SIZE];
        char url [] = "https://qss-sec/libcurl-
examples/simple.txt";
    char *dump_file_name = "https_dump_file.txt";
        char *priv_key_name = "toolbox.pem";
        char *ca_bundle_file = "curl-ca-bundle.crt";

        FILE *dump_file = fopen (dump_file_name, "w");
    if (NULL == dump_file) {
      return 0;
    }
    res = curl_easy_setopt(curl, CURLOPT_ERRORBUFFER,
err_buf);
        if (CURLE_OK != res){
                goto error;
        }
        res = curl_easy_setopt(curl,
CURLOPT_VERBOSE);
    
    res = curl_easy_setopt
(curl,CURLOPT_SSLKEY,priv_key_name);
    if (CURLE_OK != res){
      goto error;
    }
    
    res = curl_easy_setopt(curl,
CURLOPT_SSLKEYPASSWD, "toolbox");
    if (CURLE_OK != res){
      goto error;
    }
        res = curl_easy_setopt(curl, CURLOPT_CAINFO,
ca_bundle_file);

        res = curl_easy_setopt(curl, CURLOPT_URL,
url);
        if (CURLE_OK != res){
                goto error;
        }
        res = curl_easy_setopt(curl,
CURLOPT_WRITEDATA, dump_file);
        if (CURLE_OK != res){
                goto error;
        }
        
    
        res = curl_easy_perform(curl);
        if (CURLE_OK != res){
                goto error;
        }
    if (NULL != dump_file){
      fclose(dump_file);
    }
    return 1;
        error:
                fprintf(stderr, "curl error: %s\n",
err_buf);
        if (NULL != dump_file) fclose (dump_file);
                return 0;

}

int main(void)
{
  int irval = 0;
  CURL *curl = curl_easy_init();

  if(NULL != curl) {
    irval = fetch_page(curl);
    if (irval) {
                puts("Fetching of page successfull");
        }
        curl_easy_cleanup(curl);
  }
  curl_global_cleanup();
  return 0;
}
The output is as follows:

Doing the same with the command line tool I got this:

Eine HTTPS Seite, streng öffentlich ;-)
* Connection #0 left intact

H:\Arbeit\Toolbox\libcurl\src\https_access\Debug>

On Linux do I get the output and the dumped file.
The libcurl I use is 7.11.1 compiled with MSVC 7 and
openssl 0.97c ....

Hope someone can point me into the right direction.

Regards
Friedrich
