+.TH CURLOPT_TFTP_NO_OPTIONS 3 "19 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
+.SH NAME
+CURLOPT_TFTP_NO_OPTIONS \- Prevents TFTP options to be send with RRQs/WRQs
+.SH SYNOPSIS
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TFTP_NO_OPTIONS, long sendoptions);
+.SH DESCRIPTION
+Set \fIsendoptions\fP to 1 to exclude all TFTP options defined in RFC2347,
+RFC2348, RFC2349 from read and write requests.
+libcurl will behave like a client implementing only RFC1350, ignoring any
+protocol extensions.
+.SH DEFAULT
+0
+.SH PROTOCOLS
+TFTP
+.SH EXAMPLE
+TODO
+.SH AVAILABILITY
+Added in 7.48.0
+.SH RETURN VALUE
+Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
