docs/libcurl: generate PROTOCOLS from meta-data
Remove the PROTOCOLS section from the source files completely and
instead generate them based on the header data in the curldown files.

It also generates TLS backend information for options marked for TLS as
protocol.

NAME

CURLINFO_RESPONSE_CODE - get the last response code

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_RESPONSE_CODE, long *codep);

DESCRIPTION

Pass a pointer to a long to receive the last received HTTP, FTP, SMTP or LDAP (OpenLDAP only) response code. This option was previously known as CURLINFO_HTTP_CODE in libcurl 7.10.7 and earlier. The stored value is zero if no server response code has been received.

Note that a proxy's CONNECT response should be read with CURLINFO_HTTP_CONNECTCODE(3) and not this.

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) {
      long response_code;
      curl_easy_getinfo(curl, CURLINFO_RESPONSE_CODE, &response_code);
    }
    curl_easy_cleanup(curl);
  }
}

AVAILABILITY

Added in 7.10.8. CURLINFO_HTTP_CODE was added in 7.4.1. Support for SMTP responses added in 7.25.0, for OpenLDAP in 7.81.0.

RETURN VALUE

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