# NAME
|
||
|
|
|
||
|

# SYNOPSIS
|
||
|
|
|
||
|
|
~~~c
|
||
|
|
#include <curl/curl.h>
|
||
|
|
|
||
|
|
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_SIZE_DOWNLOAD_T,

# DESCRIPTION
|
||
|
|
|
||
|
|
Pass a pointer to a *curl_off_t* 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 from this amount.
