plucky (3) CURLOPT_TELNETOPTIONS.3.gz

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);
         }
       }
