I am trying to get an image and write it to a file. It apparently works since I
do receive an image, however the content of the image is completely wrong. When
I compare the image I get with my code and the original, I notice some
discrepencies. It seems to be relate to the wen carriage returns are encoded. I
compile the following code on windows platfrom with VC++ 7.1.

Regards,

Julien

---------------------------------------------------
#include <stdio.h>
#include <curl/curl.h>

size_t writeFunction( void *ptr, size_t size, size_t nmemb, void *stream)
{
        fwrite(ptr, size, nmemb, (FILE *)stream);
        return nmemb*size;
};

int main(void)
{
  CURL *curl;
  CURLcode res;
  FILE *destFile;

  curl = curl_easy_init();
  if(curl) {
    curl_easy_setopt(curl, CURLOPT_URL,
"http://www.google.com/images/logo.gif");
        curl_easy_setopt(curl, CURLOPT_VERBOSE, 1);

        // Open the file to write the copied file to
        destFile = fopen("myImage.gif,"w");

        // Tell libcurl where to write the file
        curl_easy_setopt(curl,CURLOPT_WRITEFUNCTION,writeFunction);
        curl_easy_setopt(curl,CURLOPT_WRITEDATA,destFile);

    res = curl_easy_perform(curl);

    /* always cleanup */
        fclose(destFile);
    curl_easy_cleanup(curl);
  }
  return 0;
}
