NAME

6       CURLOPT_TFTP_NO_OPTIONS - send no TFTP options requests
7

SYNOPSIS

9       #include <curl/curl.h>
10
11       CURLcode  curl_easy_setopt(CURL  *handle, CURLOPT_TFTP_NO_OPTIONS, long
12       onoff);
13

DESCRIPTION

15       Set onoff to 1L to exclude all TFTP options defined in RFC2347, RFC2348
16       and RFC2349 from read and write requests (RRQs/WRQs).
17
18       This  option  improves interop with some legacy servers that do not ac‐
19       knowledge or properly implement TFTP options. When this option is  used
20       CURLOPT_TFTP_BLKSIZE(3) is ignored.
