CURLOPT_CHUNK_END_FUNCTION - callback after a transfer with FTP wildcardmatch

  #include <curl/curl.h>

  long chunk_end_callback(void *ptr);

  CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CHUNK_END_FUNCTION,
                            chunk_end_callback);

Pass a pointer to your callback function, which should match the prototype shown above.

This function gets called by libcurl as soon as a part of the stream has been transferred (or skipped).

Return CURL_CHUNK_END_FUNC_OK if everything is fine or CURL_CHUNK_END_FUNC_FAIL to tell the lib to stop if some error occurred.
