CURLOPT_TELNETOPTIONS(3) Introduction to Library Functions

NAME

CURLOPT_TELNETOPTIONS - set of telnet options

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TELNETOPTIONS,
struct curl_slist *cmds);

DESCRIPTION

Provide a pointer to a curl_slist with variables to pass to the
telnet negotiations. The variables should be in the format
<option=value>. libcurl supports the options TTYPE, XDISPLOC and
NEW_ENV. See the TELNET standard for details.

Using this option multiple times makes the last set list override the
previous ones. Set it to NULL to disable its use again.

libcurl does not copy the list, it needs to be kept around until
after the transfer has completed.

DEFAULT

NULL

PROTOCOLS

This functionality affects telnet only

EXAMPLE

int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
CURLcode res;
struct curl_slist *options;
options = curl_slist_append(NULL, "TTTYPE=vt100");
options = curl_slist_append(options, "USER=foobar");
curl_easy_setopt(curl, CURLOPT_URL, "telnet://example.com/");
curl_easy_setopt(curl, CURLOPT_TELNETOPTIONS, options);
res = curl_easy_perform(curl);
curl_easy_cleanup(curl);
curl_slist_free_all(options);
}
}
