NAME

SYNOPSIS

9       #include <curl/curl.h>
10
11       CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_SIZE_DOWNLOAD, double *dlp);
12

DESCRIPTION

14       Pass  a  pointer  to a double to receive the total amount of bytes that
15       were downloaded.  The amount is only for the latest transfer  and  will
16       be  reset again for each new transfer. This counts actual payload data,
17       what's also commonly called body. All meta and header data are excluded
18       and will not be counted in this number.
19
20       CURLINFO_SIZE_DOWNLOAD_T(3)  is a newer replacement that returns a more
21       sensible variable type.
