SYNOPSIS

11       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TFTP_NO_OPTIONS, long onoff);
12

DESCRIPTION

14       Set  onoff  to  1L to exclude all TFTP options defined in RFC 2347, RFC
15       2348 and RFC 2349 from read and write requests.
16
17       This option improves interoperability with legacy servers that  do  not
18       acknowledge  or  properly  implement  TFTP options. When this option is
19       used CURLOPT_TFTP_BLKSIZE(3) is ignored.
