CURLOPT_NOBODY(3)					     curl_easy_setopt options						 CURLOPT_NOBODY(3)

NAME

       CURLOPT_NOBODY - do the download request without getting the body

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_NOBODY, long opt);

DESCRIPTION

       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.

       Enabling this option means asking for a download but without a body.

DEFAULT

       0, the body is transferred

PROTOCOLS

       Most

EXAMPLE

       curl = curl_easy_init();
       if(curl) {
	 curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");

	 /* get us the resource without a body! */
	 curl_easy_setopt(curl, CURLOPT_NOBODY, 1L);

	 /* Perform the request */
	 curl_easy_perform(curl);
       }

AVAILABILITY

       Always

RETURN VALUE

       Returns CURLE_OK
