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 onoff);
12

DESCRIPTION

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