CURLINFO_SIZE_DOWNLOAD(3)           libcurl          CURLINFO_SIZE_DOWNLOAD(3)


NAME

       CURLINFO_SIZE_DOWNLOAD - get the number of downloaded bytes


SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_SIZE_DOWNLOAD, double *dlp);


DESCRIPTION

       Pass a pointer to a double to receive the total amount of bytes that
       were downloaded.  The amount is only for the latest transfer and will
       be reset again for each new transfer. This counts actual payload data,
       what's also commonly called body. All meta and header data are excluded
       and will not be counted in this number.

       CURLINFO_SIZE_DOWNLOAD_T(3) is a newer replacement that returns a more
       sensible variable type.


PROTOCOLS

       All


EXAMPLE

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

         /* Perform the request */
         res = curl_easy_perform(curl);

         if(!res) {
           /* check the size */
           double dl;
           res = curl_easy_getinfo(curl, CURLINFO_SIZE_DOWNLOAD, &dl);
           if(!res) {
             printf("Downloaded %.0f bytes\n", cl);
           }
         }
       }
