# NAME
|
||
|
|
|
||
|
|
CURLOPT_FTP_ALTERNATIVE_TO_USER - command to use instead of USER with FTP
|
||
|
|
|
||
|
|
# SYNOPSIS
|
||
|
|
|
||
|
|
~~~c
|
||
|
|
#include <curl/curl.h>
|
||
|
|
|
||
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FTP_ALTERNATIVE_TO_USER,

# 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
|
||
|
|
Tumbleweed's Secure Transport FTPS server using client certificates for
|
||
|
|
authentication.
|
||
|
|
|
||
|
|
The application does not have to keep the string around after setting this
|
||
|
|
option.

||
|
|
|
||
|
|
# DEFAULT
|
||
|
|
|
||
|
|
NULL
