korzystam z takiego programu:

#include <stdio.h>

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

 * This is an example showing how to get a single file from an FTP server.
 * It delays the actual destination file creation until the first write
 * callback so that it won't create an empty file in case the remote file
 * doesn't exist or something else fails.

struct FtpFile {
  const char *filename;
  FILE *stream;

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

int main(void)
  CURL *curl;
  CURLcode res;
  struct FtpFile ftpfile={
    "data.txt", /* name to store the file as if succesful */ 


  curl = curl_easy_init();
  if(curl) {
     * You better replace the URL with one that works!
    curl_easy_setopt(curl, CURLOPT_URL,
    /* Define our callback to get called when there's data to be written */ 
    curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, my_fwrite);
    /* Set a pointer to our struct to pass to the callback */ 
    curl_easy_setopt(curl, CURLOPT_WRITEDATA, &ftpfile);

    /* Switch on full protocol/debug output */ 
    curl_easy_setopt(curl, CURLOPT_VERBOSE, 1L);

    res = curl_easy_perform(curl);

    /* always cleanup */ 

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

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


  return 0;

jednak nie tworzy on pliku data.txt z kodem strony,

w konsoli mam:
about to connect() to ftp.wp.pl port 21 (#0)
trying connected
conected to ftp.wp.pl ( port 21 (#0)
select/poll error
closing connection #0
*out of memory
curl told us 27

proszę o pomoc w doprowadzeniu tego do ładu.

Spod adresu ftp://ftp.wp.pl strony www nie ściągniesz. To nie ten protokół.
