try this program

I compiled with simply gcc -lcurl test.c

========= test.c ===============

#include <stdio.h>
#include <stdlib.h>
#include <curl/curl.h>

size_t callback(void *clientp, double dltotal, double dlnow,
                double ultotal, double ulnow)
{
    printf("dltotal %f, dlnow %f, ultotal %f, ulnow %f\n",
           dltotal, dlnow, ultotal, ulnow);

    return 0;
}

int main()
{
    CURL* curl;
    int res;
    FILE* m_fstream;
    
    curl = curl_easy_init();

    m_fstream = fopen("/home/wweng/Test/vim.tar.bz2", "wb");

    if (!m_fstream)
    {
        printf("Error in opening file\n");
        return 0;
    }
    
    curl_easy_setopt(curl, CURLOPT_VERBOSE, 1);
    curl_easy_setopt(curl, CURLOPT_URL,
"ftp://ftp.vim.org/pub/vim/unix/vim-6.2.tar.bz2");
    curl_easy_setopt(curl, CURLOPT_WRITEDATA, m_fstream);
    curl_easy_setopt(curl, CURLOPT_NOPROGRESS, 0);
    curl_easy_setopt(curl, CURLOPT_PROGRESSFUNCTION, callback);

    printf("Begin curl_easy_perform\n");
    res = curl_easy_perform(curl);

    if (m_fstream)
        fclose(m_fstream);
    
    curl_easy_cleanup(curl);

    return 1;
}

========== end of test.c ===================

Try to unplug the cable in the middle of transfer, you will see that the
progress function gets called over and over again, the message gets
printed out. And if you plug the cable back in, the transfer resumes, and
goes on.

Please DO NOT fix it if you think libcurl should have quitted. :) This
particular behavior is quite userful to me, but if we can have some
better control, (such as an option of setting how many times libcurl is
going to "retry") it is even better!

Thanks
