curl_easy_setopt options CURLOPT_FTP_ALTERNATIVE_TO_USER(3) 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.
