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();

/* Perform the request */
