- 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

CURLOPT_MAXFILESIZE_LARGE - maximum file size allowed to download

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAXFILESIZE_LARGE,
                          curl_off_t size);

DESCRIPTION

Pass a curl_off_t as parameter. This specifies the maximum accepted size (in bytes) of a file to download. If the file requested is found larger than this value, the transfer is aborted and CURLE_FILESIZE_EXCEEDED is returned. Passing a zero size disables this, and passing a negative size yields a CURLE_BAD_FUNCTION_ARGUMENT.

The file size is not always known prior to the download start, and for such transfers this option has no effect - even if the file transfer eventually ends up being larger than this given limit.

Since 8.4.0, this option also stops ongoing transfers if they reach this threshold.

DEFAULT

0, meaning disabled.

%PROTOCOLS%

EXAMPLE

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode ret;
    curl_off_t ridiculous = (curl_off_t)1 << 48;
    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
    /* refuse to download if larger than ridiculous */
    curl_easy_setopt(curl, CURLOPT_MAXFILESIZE_LARGE, ridiculous);
    ret = curl_easy_perform(curl);
  }
}

%AVAILABILITY%

RETURN VALUE

Returns CURLE_OK if the option is supported, CURLE_UNKNOWN_OPTION if not, or CURLE_BAD_FUNCTION_ARGUMENT if the size passed is invalid.
