CURLOPT_RESUME_FROM - set a point to resume transfer from #include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_RESUME_FROM, long from); Pass a long as parameter. It contains the offset in number of bytes that you want the transfer to start from. Set this option to 0 to make the transfer start from the beginning (effectively disabling resume). For FTP, set this option to -1 to make the transfer start from the end of the target file (useful to continue an interrupted upload). When doing uploads with FTP, the resume position is where in the local/source file libcurl should try to resume the upload from and it will then append the source file to the remote target file. If you need to resume a transfer beyond the 2GB limit, use CURLOPT_RESUME_FROM_LARGE(3) instead. 0, not used HTTP, FTP, SFTP, FILE

CURL *curl = curl_easy_init();
if(curl) {
 curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com");

 /* resume upload at byte index 200 */
 curl_easy_setopt(curl, CURLOPT_RESUME_FROM, 200L);

 /* ask for upload */
 curl_easy_setopt(curl, CURLOPT_UPLOAD, 1L);

 /* set total data amount to expect */
 curl_easy_setopt(curl, CURLOPT_INFILESIZE, size_of_file);

 /* Perform the request */
 curl_easy_perform(curl);
}

Always Returns CURLE_OK CURLOPT_RESUME_FROM_LARGE "(3), " CURLOPT_RANGE "(3), " CURLOPT_INFILESIZE "(3), "
