NAME
CURLOPT_TFTP_NO_OPTIONS - send no TFTP options requests
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TFTP_NO_OPTIONS, long onoff);
DESCRIPTION
Set onoff to 1L to exclude all TFTP options defined in RFC2347, RFC2348
and RFC2349 from read and write requests (RRQs/WRQs).
This option improves interop with some legacy servers that do not ac-
knowledge or properly implement TFTP options. When this option is used
CURLOPT_TFTP_BLKSIZE(3) is ignored.
DEFAULT
0

if(curl) {
FILE *fp = fopen("foo.bin", "wb");
