Name
CURLOPT_LOGIN_OPTIONS - 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 null-terminated options string to use for the transfer.
For more information about the login options please see RFC 2384, RFC 5092 and the IETF draft draft-earhart-url-smtp-00.txt.
CURLOPT_LOGIN_OPTIONS 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 option.
The application does not have to keep the string around after setting this option.

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); }
