CURLINFO_SIZE_DOWNLOAD(3)  Library Functions Manual  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 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.
