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.
