Making New Directory with libcurl - c++

Question

I have been tinkering with libcurl and so far its nice. I have some few things that are reeally confusing me. I need to create a directory to remote server and here are problems
What do I pass in CURLOPT_URL? Is it a root URL or full ith directory?
I want ripple effect in creating directory that is, if I have diectory /abc/def/ghi then they should be created if they do not exists. I have tried CURLOPT_FTP_CREATE_MISSING_DIRS but does not work.
Tried MKD it fails and I cannot say for sure why. Below are the relevant code and log from app
CODE
CURL* handle = curl_easy_init();
SetHandleOptions(handle); //set options
CURLcode res;
wxString uploadUrl =....;//full URL with path like ftp.xyz.com/public_html/dir1/
wxString command1 = "MKD "+uploadUrl;
wxString command2 = "CWD "+uploadUrl;
struct curl_slist *headers = NULL;
headers = curl_slist_append(headers, command1.c_str());
headers = curl_slist_append(headers, command2.c_str());
curl_easy_setopt(handle, CURLOPT_QUOTE, headers);
const char* uploadUrlStr = uploadUrl.c_str();
if(handle)
{
//do file upload here
/* upload to this place */
curl_easy_setopt(handle, CURLOPT_URL, uploadUrlStr);
/* enable verbose for easier tracing */
curl_easy_setopt(handle, CURLOPT_VERBOSE, 1L);
curl_easy_setopt(handle, CURLOPT_FTP_CREATE_MISSING_DIRS, 1L);
curl_easy_setopt(handle, CURLOPT_QUOTE, headers);
res = curl_easy_perform(handle);
if(res==CURLE_OK)
{
SendMessage(_("Successfully Created Directory: ")+uploadUrl, HERROR_TYPE_WARNING);
}
else
{
//send error message
wxString str(curl_easy_strerror(res));
SendMessage(str);
}
/* always cleanup */
curl_easy_cleanup(handle);
}
else
{
SendMessage(_("Could Not Connect to Server: Invalid Handle"), HERROR_TYPE_CRITICAL);
}
curl_slist_free_all(headers);

Answer 1

Make sure the Paths are in form of /public_html/somedir not ftp://ftp.somesite.com/public_html/somedir
That is what was going wrong with my code. So I resolved by removing URL. I believe there should be a section on libcurl explaining expected URLs format. I will contribute that once I fully grasp it!
