- make DEFAULT sections less repetitive

- make historic mentions use HISTORY

- generate the protocols section on `# %PROTOCOLS%` instead of guessing
  where to put it

- generate the availability section on `# %AVAILABILITY%` instead of
  guessing where to put it

- make the protocols section more verbose

NAME

CURLINFO_SIZE_DOWNLOAD_T - get the number of downloaded bytes

SYNOPSIS

#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

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 */
      curl_off_t dl;
      res = curl_easy_getinfo(curl, CURLINFO_SIZE_DOWNLOAD_T, &dl);
      if(!res) {
        printf("Downloaded %" CURL_FORMAT_CURL_OFF_T " bytes\n", dl);
      }
    }
  }
}

%AVAILABILITY%
