CURLOPT_NOBODY: do the download request without getting the body
NAME
CURLOPT_NOBODY - do the download request without getting the bodySYNOPSIS
#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 transferredPROTOCOLS
MostEXAMPLE
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);
