Please see the following program, in which I use 10002 for CURLOPT_URL.
If you'd like to know why I use 10002, please understand definitions of CINIT and
CURLOPT_URL in curl.h on your own.

Regards,

require 'dl/import'
require 'dl/struct'

module Curl
	extend DL::Importable
	dlload "libcurl.dll"

	typealias('CURL', 'void')
	typealias('CURLOPT', 'long')
         typealias('CURLcode', 'int')

	extern "CURL *curl_easy_init()"
	extern "char *curl_version()"
	extern "void *curl_version_info(int)"
	extern "CURLcode curl_easy_setopt(CURL *, CURLOPT, char *)"
	extern "void curl_easy_cleanup(CURL *)"
         extern "CURLcode curl_easy_perform(CURL *)"

	VersionInfoData = struct [
		"int age",
		"char *version",
		"uint version_num",
		"char *host",
		"int features",
		"char *ssl_version",
		"long ssl_version_num",
		"char *libz_version",
		"char **protocols"
	]
end

handle = Curl.curl_easy_init

CURLOPT_URL = 10002 # I don't know the value
URL = "http://www.google.com/"
p Curl.curl_easy_setopt(handle, CURLOPT_URL, URL)

p Curl.curl_easy_perform(handle)
# This also fails
# Documentation is at http://curl.mirror.internet.tp/libcurl/c/curl_easy_cleanup.html
Curl.curl_easy_cleanup(handle)
