CURLOPT_NOBODY − do the download request without getting the body
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_NOBODY, long opt);
A long parameter set to 1 tells libcurl to not include the body-part in the output when doing what would otherwise be a download. For HTTP(S), this makes libcurl do a HEAD request. For most other protocols it means just not asking to transfer the body data.
For HTTP operations when CURLOPT_NOBODY(3) has been set, unsetting the option (with 0) will make it a GET again - only if the method is still set to be HEAD. The proper way to get back to a GET request is to set CURLOPT_HTTPGET(3) and for other methods, use the POST ur UPLOAD options.
Enabling CURLOPT_NOBODY(3) means asking for a download without a body.
If you do a transfer with HTTP that involves a method other than HEAD, you will get a body (unless the resource and server sends a zero byte body for the specific URL you request).
0, the body is transferred
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
/* get us the
resource without a body - use HEAD! */
curl_easy_setopt(curl, CURLOPT_NOBODY, 1L);

CURLOPT_HTTPGET(3), CURLOPT_POSTFIELDS(3), CURLOPT_UPLOAD(3), CURLOPT_REQUEST_TARGET(3), CURLOPT_MIMEPOST(3),
