SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FTP_ALTERNATIVE_TO_USER,
                          char *cmd);

 

DESCRIPTION

Pass a char pointer as parameter, pointing to a string which is used to authenticate if the usual FTP "USER user" and "PASS password" negotiation fails. This is currently only known to be required when connecting to Tumbleweedaqs Secure Transport FTPS server using client certificates for authentication.

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

    curl_easy_setopt(curl, CURLOPT_FTP_ALTERNATIVE_TO_USER, "two users");
