CURLOPT_HEADER(3)					     curl_easy_setopt options						 CURLOPT_HEADER(3)

NAME
       CURLOPT_HEADER - pass headers to the data stream

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HEADER, long onoff);

DESCRIPTION
       Pass  in onoff set to 1 to tell the library to include the header in the body output for requests with this handle. This option is relevant
       for protocols that actually have headers or other meta-data (like HTTP and FTP).

       When asking to get the header info passed to the same callback as the body, it is not possible to accurately separate  them  again  without
       detailed knowledge about the protocol in use.

       It is often better to use CURLOPT_HEADERFUNCTION(3) to get the header data separately.

       While named confusingly similar, CURLOPT_HTTPHEADER(3) is used to set custom HTTP headers!

	 curl_easy_perform(curl);
       }

       Returns CURLE_OK.
