+ * NAME curl_open()
+ *
+ * DESCRIPTION
+ *
+ * Opens a general curl session. It does not try to connect or do anything
+ * on the network because of this call. The specified URL is only required
+ * to enable curl to figure out what protocol to "activate".
+ *
+ * A session should be looked upon as a series of requests to a single host.  A
+ * session interacts with one host only, using one single protocol.
+ *
+ * The URL is not required. If set to "" or NULL, it can still be set later
+ * using the curl_setopt() function. If the curl_connect() function is called
+ * without the URL being known, it will return error.
+ *
+ * EXAMPLE
+ *
+ * CURLcode result;
+ * CURL *curl;
+ * result = curl_open(&curl, "http://curl.haxx.nu/libcurl/");
+ * if(result != CURL_OK) {
+ *   return result;

+ * NAME curl_do()
+ *
+ * DESCRIPTION
+ *
+ * (Note: May 3rd 2000: this function does not currently allow you to
+ * specify a document, it will use the one set previously)
+ *
+ * This function asks for the particular document, file or resource that
+ * resides on the server we have connected to. You may specify a full URL,
+ * just an absolute path or even a relative path. That means, if you're just
+ * getting one file from the remote site, you can use the same URL as input
+ * for both curl_open() as well as for this function.
+ *
+ * In the even there is a host name, port number, user name or password parts
+ * in the URL, you can use the 'flags' argument to ignore them completely, or
+ * at your choice, make the function fail if you're trying to get a URL from
+ * different host than you connected to with curl_connect().
+ *
+ * You can only get one document at a time using the same connection. When one
+ * document has been received you can although request again.
+ *
+ * When the transfer is done, curl_done() MUST be called.
+ *
+ * EXAMPLE
+ *
+ * CURLCode result;
+ * char *url;
+ * CURLconnect *connect;
+ * result = curl_do(connect, url, CURL_DO_NONE); */

+ * char *url;
