bionic (3) CURLINFO_SIZE_DOWNLOAD.3.gz

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.

EXAMPLE

       CURL *curl = curl_easy_init();
       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, "http://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);
           }
         }
