plucky (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 gets reset again for each new transfer.  This  counts  actual  payload  data,
       what's also commonly called body. All meta and header data is excluded and not included in this number.

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

           res = curl_easy_perform(curl);

           if(!res) {
             /* check the size */
