- 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

Closes #14227

NAME

CURLOPT_MAX_RECV_SPEED_LARGE - rate limit data download speed

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAX_RECV_SPEED_LARGE,
                          curl_off_t maxspeed);

DESCRIPTION

Pass a curl_off_t as parameter. If a download exceeds this maxspeed (counted in bytes per second) the transfer pauses to keep the average speed less than or equal to the parameter value. Defaults to unlimited speed.

This is not an exact science. libcurl attempts to keep the average speed below the given threshold over a period time.

If you set maxspeed to a value lower than CURLOPT_BUFFERSIZE(3), libcurl might download faster than the set limit initially.

This option does not affect transfer speeds done with FILE:// URLs.

DEFAULT

0, disabled

%PROTOCOLS%

EXAMPLE

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode ret;
    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
    /* cap the download speed to 31415 bytes/sec */
    curl_easy_setopt(curl, CURLOPT_MAX_RECV_SPEED_LARGE, (curl_off_t)31415);
    ret = curl_easy_perform(curl);
  }
}

%AVAILABILITY%

RETURN VALUE

Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
