Libcurl display log messages even the CURLOPT_VERBOSE is not activated

I'm using libcurl to send http message.

I developed the following function in which I initiate curl options and then perform a send of a http message. the option CURLOPT_VERBOSE is not activated in the following code. But when executing the following function, the received http message is displayed in the verbose. How I can fix that ?

http_lightweight_notification(char *msg_out, int msg_out_len)
{
    static CURL *n_curl;
    CURLcode res;
    struct curl_slist *chunk = NULL;
    char *url="http://192.168.1.133:8080";
    char buf[SIGNATURE_LEN + sizeof("Signature: ")] = "Signature: ";
    char *signature = buf + sizeof("Signature: ") - 1;

    if (!msg_out) return -1;
    n_curl = curl_easy_init();
    if (!n_curl) return -1;

    signature_hmac_sha1(msg_out, "anykey", signature);

    chunk = curl_slist_append(chunk, "Content-Type: text/xml; charset=utf-8");
    if (!chunk) return -1;
    chunk = curl_slist_append(chunk, "Accept:");
    if (!chunk) return -1;
    chunk = curl_slist_append(chunk, buf);
    if (!chunk) return -1;

    curl_easy_setopt(n_curl, CURLOPT_URL, url);
    curl_easy_setopt(n_curl, CURLOPT_HTTPHEADER, chunk);
    curl_easy_setopt(n_curl, CURLOPT_TIMEOUT, 30);
    curl_easy_setopt(n_curl, CURLOPT_CONNECTTIMEOUT, 30);

    curl_easy_setopt(n_curl, CURLOPT_POSTFIELDS, msg_out);
    curl_easy_setopt(n_curl, CURLOPT_POSTFIELDSIZE, (long) msg_out_len);

# if 0
    curl_easy_setopt(n_curl, CURLOPT_VERBOSE, 1L);
# endif

    res = curl_easy_perform(n_curl);
    if (chunk) {
        curl_slist_free_all(chunk);
        chunk = NULL;
    }
    curl_easy_cleanup(n_curl);
    curl_global_cleanup();

    if (res) return -1;
    return 0;
}

The verbose output is:

That's not the verbose output, that's the body of the content you receive.

You inhibit the content to get sent to stdout (which is the default) by setting the CURLOPT_WRITEFUNCTION to receive the data, or possibly set CURLOPT_WRITEDATA to a different FILE * handle.

Shown in the getinmemory.c example among others.
