# NAME
CURLINFO_SIZE_DOWNLOAD_T - number of downloaded bytes
# SYNOPSIS
~~~c
#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_SIZE_DOWNLOAD_T,
curl_off_t *dlp);
~~~
# 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.
# %PROTOCOLS%
# EXAMPLE
~~~c
int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
CURLcode result;
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
/* Perform the request */
result = curl_easy_perform(curl);
if(!result) {
/* check the size */
curl_off_t dl;
result = curl_easy_getinfo(curl, CURLINFO_SIZE_DOWNLOAD_T, &dl);
if(!result) {
printf("Downloaded %" CURL_FORMAT_CURL_OFF_T " bytes\n", dl);
}
}
}
}
~~~
# %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).
