- 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

CURLINFO_SCHEME - get the URL scheme (sometimes called protocol) used in the connection

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_SCHEME, char **scheme);

DESCRIPTION

Pass a pointer to a char pointer to receive the pointer to a null-terminated string holding the URL scheme used for the most recent connection done with this CURL handle.

The scheme pointer is NULL or points to private memory. You MUST NOT free - it gets freed when you call curl_easy_cleanup(3) on the corresponding CURL handle.

The returned scheme might be upper or lowercase. Do comparisons case insensitively.

%PROTOCOLS%

EXAMPLE

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode res;
    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
    res = curl_easy_perform(curl);
    if(res == CURLE_OK) {
      char *scheme = NULL;
      curl_easy_getinfo(curl, CURLINFO_SCHEME, &scheme);
      if(scheme)
        printf("scheme: %s\n", scheme); /* scheme: HTTP */
    }
    curl_easy_cleanup(curl);
  }
}

%AVAILABILITY%

RETURN VALUE

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