CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_FTP_ENTRY_PATH, char **path);
DESCRIPTIONPass a pointer to a char pointer to receive a pointer to a string holding the path of the entry path. That is the initial path libcurl ended up in when logging on to the remote FTP server. This stores a NULL as pointer if something is wrong.
The path pointer will be NULL or pointing to private memory you MUST NOT free - it gets freed when you call curl_easy_cleanup(3) on the corresponding CURL handle.
