       CURLOPT_LOGIN_OPTIONS - set login options

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_LOGIN_OPTIONS, char *options);

DESCRIPTION

       Pass a char * as parameter, which should be pointing to the zero terminated options string
       to use for the transfer.

       For more information about the login options please see RFC2384, RFC5092  and  IETF  draft
       draft-earhart-url-smtp-00.txt

       CURLOPT_LOGIN_OPTIONS(3)  can  be used to set protocol specific login options, such as the
       preferred authentication mechanism via "AUTH=NTLM" or "AUTH=*",  and  should  be  used  in
       conjunction with the CURLOPT_USERNAME(3) option.

       The application does not have to keep the string around after setting this option.

DEFAULT

       NULL

PROTOCOLS

       Only IMAP, POP3 and SMTP support login options.

EXAMPLE

       CURL *curl = curl_easy_init();
       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, "smtp://example.com/");
         curl_easy_setopt(curl, CURLOPT_LOGIN_OPTIONS, "AUTH=*");
         ret = curl_easy_perform(curl);
         curl_easy_cleanup(curl);
       }
