Downloading all files in directory using libcurl

I am new to the libcurl and found a way to download a single file from the ftp server. Now my requirement is to download all files in a directory and i guess it was not supported by libcurl. Kindly suggest on libcurl how to download all files in directory or is there any oth开发者_如何学Pythoner library similar to libcurl?

Thanks in advance.

Here is a sample piece of code.

static size_t GetFilesList_response(void *ptr, size_t size, size_t nmemb, void *data)
{
    FILE *writehere = (FILE *)data;
    return fwrite(ptr, size, nmemb, writehere);
}

bool FTPWithcURL::GetFilesList(char* tempFile)
{
    CURL *curl;
    CURLcode res;
    FILE *ftpfile;

    /* local file name to store the file as */
    ftpfile = fopen(tempFile, "wb"); /* b is binary, needed on win32 */ 

    curl = curl_easy_init();
    if(curl) 
    {
        curl_easy_setopt(curl, CURLOPT_URL, "ftp://ftp.example.com");
        curl_easy_setopt(curl, CURLOPT_USERPWD, "username:password");
        curl_easy_setopt(curl, CURLOPT_WRITEDATA, ftpfile);
        // added to @Tombart suggestion
        curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, GetFilesList_response);
        curl_easy_setopt(curl, CURLOPT_DIRLISTONLY, 1);

        res = curl_easy_perform(curl);

        curl_easy_cleanup(curl);
    }

    fclose(ftpfile); //


    if(CURLE_OK != res) 
        return false;

    return true;
}

You need the list of files on the FTP server. Which isn't straightforward as each FTP server might return a different format of file listing...

Anyway, the ftpgetresp.c example shows a way to do it, I think. FTP Custom CUSTOMREQUEST suggests another way.

Just use CURLOPT_WILDCARDMATCH feature. Sample code: https://curl.haxx.se/libcurl/c/ftp-wildcard.html
