NAME
CURLOPT_FTP_ALTERNATIVE_TO_USER - command to use instead of USER with
FTP
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FTP_ALTERNATIVE_TO_USER,
char *cmd);
DESCRIPTION
Pass a char * as parameter, pointing to a string which will be used to
authenticate if the usual FTP "USER user" and "PASS password" negotia-
tion 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
PROTOCOLS
FTP
EXAMPLE
CURL *curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/foo.bin");
curl_easy_setopt(curl, CURLOPT_FTP_ALTERNATIVE_TO_USER, "two users");
ret = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
AVAILABILITY
Added in 7.15.5
RETURN VALUE
Returns CURLE_OK if the option is supported, CURLE_UNKNOWN_OPTION if
not, or CURLE_OUT_OF_MEMORY if there was insufficient heap space.
