# 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.
# %PROTOCOLS%
# EXAMPLE
~~~c
int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
CURLcode res;
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
/* Perform the request */
res = curl_easy_perform(curl);
if(!res) {
/* check the size */
double dl;
res = curl_easy_getinfo(curl, CURLINFO_SIZE_DOWNLOAD, &dl);
if(!res) {
printf("Downloaded %.0f bytes\n", dl);
}
}
}
}
~~~
# DEPRECATED
Deprecated since 7.55.0.
# %AVAILABILITY%
# RETURN VALUE
curl_easy_setopt(3) returns a CURLcode indicating success or error.
CURLE_OK (0) means everything was OK, non-zero means an error occurred, see
libcurl-errors(3).
