Expand a little. - mention the type name of the return code - avoid stating which exact return codes that might be returned, as that varies over time, builds and conditions - avoid stating some always return OK - refer to the manpage documenting all the return codes Closes #15900

# NAME
|
|
|
|
CURLOPT_TFTP_NO_OPTIONS - send no TFTP options requests
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#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 RFC 2347,
|
|
RFC 2348 and RFC 2349 from read and write requests.
|
|
|
|
This option improves interoperability with legacy servers that do not
|
|
acknowledge or properly implement TFTP options. When this option is used
|
|
CURLOPT_TFTP_BLKSIZE(3) is ignored.
