#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_CONTENT_LENGTH_UPLOAD,
double *content_length);

# DESCRIPTION
Pass a pointer to a double to receive the specified size of the upload. Since

more sensible variable type.

/* Perform the upload */
res = curl_easy_perform(curl);
if(!res) {
/* check the size */
double cl;
res = curl_easy_getinfo(curl, CURLINFO_CONTENT_LENGTH_UPLOAD, &cl);
if(!res) {
printf("Size: %.0f\n", cl);
