# NAME
|
||
|
|
|
||
|
|
CURLINFO_SIZE_DOWNLOAD - get the number of downloaded bytes
|
||
|
|
|
||
|
|
# SYNOPSIS
|
||
|
|
|
||
|
|
~~~c
|
||
|
|
#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.
