getFileName()

RRString rr::RRHash::getFileName	(	unsigned	version,
		const char *	prefix,
		const char *	postfix
	)		const

version	Additional number melted into hash, different versions produce different filenames.
prefix	Optional prefix (e.g. "c:/path/") of returned filename. If nullptr, temporary directory is used.
postfix	Optional postfix (e.g. ".extension") of returned filename. If nullptr, no postfix is appended.
