Hi all,

I'm quite new to the world of C so I merely hacked this code together (it was
more a cut'n paste) ...

#include <stdio.h>

#include <curl/curl.h>
#include <curl/types.h>
#include <curl/easy.h>

struct SftpFile
{
        const char *filename;
        FILE *stream;
};

static size_t my_fwrite(void *buffer, size_t size, size_t nmemb, void *stream)
{
  struct SftpFile *out=(struct SftpFile *)stream;
  if(out && !out->stream) {
    /* open file for writing */
    out->stream=fopen(out->filename, "wb");
    if(!out->stream)
      fprintf(stderr, "failure, can't open file to write");
      return -1;
  }
  return fwrite(buffer, size, nmemb, out->stream);
}

int main(void)
{
  CURL *curl;
  CURLcode res;
  struct SftpFile sftpfile={"core-n", /* name to store the file as if succesful
*/NULL};

  curl = curl_easy_init();
  if(curl)
        {
        curl_easy_setopt(curl, CURLOPT_URL,"sftp://192.168.0.1/~/tmp/core");
        curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, my_fwrite);
        curl_easy_setopt(curl, CURLOPT_WRITEDATA, &sftpfile);
        //curl_easy_setopt(curl, CURLOPT_SSH_AUTH_TYPES, CURLSSH_AUTH_PASSWORD);
        curl_easy_setopt(curl, CURLOPT_USERPWD, "hlds:counter#12");

        curl_easy_setopt(curl, CURLOPT_VERBOSE, 1);
        curl_easy_setopt(curl, CURLOPT_DEBUGFUNCTION, 1);

        res = curl_easy_perform(curl);
        curl_easy_cleanup(curl);

        if(CURLE_OK != res)
                {
        fprintf(stderr, "curl told us %d\n", res);
                }
        }

   if(sftpfile.stream)
   fclose(sftpfile.stream); /* close the local file */

   return 0;
}

Basically the file should just get the corefile out of the /tmp direcxtory and
download it to my box via sftp (only ssh access is permitted)
The code compile without any complains, warnings or infos, but core-dumps when
executed.
From the dump I can see Error 58 ....
Any ideas ?

TIA
