# CURLINFO\_SIZE\_DOWNLOAD(3)

get the number of downloaded bytes

## 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)](/CURLINFO_SIZE_DOWNLOAD_T/3.md)* is a newer replacement that returns a more sensible variable type.

## PROTOCOLS

All

## EXAMPLE

```
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);
      }
    }
  }
}
