.TH CURLOPT_HEADER 3 "16 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
.SH NAME
CURLOPT_HEADER \- pass headers to the data stream
.SH SYNOPSIS
#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HEADER, long onoff);
.SH DESCRIPTION
Pass in \fIonoff\fP set to 1 to tell the library to include the header in the
body output for requests with this \fIhandle\fP. 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 \fICURLOPT_HEADERFUNCTION(3)\fP to get the header
data separately.
.SH DEFAULT
0
.SH RETURN VALUE
Returns CURLE_OK.
