I want to upload a large binary file to http server

In order to improve the speed£¬i want to divide the file into several pars, for example FILE*+ offset
I dont't know hot to do , such as use function "curl_formadd"

curl_formadd(&pFormPost,
                     &pLastElem,
                      CURLFORM_COPYNAME,
                       "ufile01",
                     CURLFORM_FILE,
                    localfile,
                    CURLFORM_CONTENTTYPE,
                     "application/octet-stream",
                    CURLFORM_END);

Its sixth parameters is local file path , does it support file handle ,such as FILE *
If it does not support, is there any other methods

thank you
