[out]	dirs	The directories in dir. Won't be used if nullptr.
	mode	Determines whether the entire path or just the filename is retrieved.
	filter	Determines if we skip images and sounds directories.
	reorder	Triggers the special handling of _main.cfg and _final.cfg.
[out]	checksum	Can be used to store checksum info.

◆ nearest_extant_parent()

std::string filesystem::nearest_extant_parent ( const std::string & file )

Finds the nearest parent in existence for a file or directory.

Note: The file's own existence is not checked.

Returns: An absolute path to the closest parent of the given path, or an empty string if none could be found. While on POSIX platforms this cannot happen (unless the original path was already empty), on Windows it might be the case that the original path refers to a drive letter or network share that does not exist.

◆ normalize_path()

std::string filesystem::normalize_path	(	const std::string &	path,

Returns the absolute path of a file.

Parameters

path	Original path.
normalize_separators	Whether to substitute path separators with the platform's preferred format.
resolve_dot_entries	Whether to resolve . and .. directory entries. This requires path to refer to a valid existing object.

Returns: An absolute path – that is, a path that is independent of the current working directory for the process. If resolve_dot_entries is set to true, the returned path has . and .. components resolved; however, if resolution fails because a component does not exist, an empty string is returned instead.
