restore()

int restore	(	FILE *	disk,

If the first argument parses as a numeric ID, restores that snapshot. Otherwise treats it as a name and disambiguates if multiple snapshots share the same name, printing a table of candidates with deletion timestamps.

Parameters

disk	Open filesystem image.
sb	Loaded superblock.
args	argv-like vector; id or name in args[1], optional dest dir in args[2].
