NAME

CURLOPT_TFTP_NO_OPTIONS - Do not send 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 acknowledge or properly implement TFTP options. When this option is used CURLOPT_TFTP_BLKSIZE(3) is ignored.

DEFAULT

0

curl_easy_setopt(curl, CURLOPT_URL, "tftp://example.com/foo.bin");
/* do not send TFTP options requests */ curl_easy_setopt(curl, CURLOPT_TFTP_NO_OPTIONS, 1L);
