4.8 History
C pointer type representing file system history objects. A history
object represents some event when a file system node is modified or
copied, which doesn’t necessarily mean that the node’s contents or
properties change with every history event.
Checks whether the given obj is a file system history
object.
Retrieves a history object for the node at path below
root.
(fs-history-prev history cross-copies?) → (or/c fs-history? #f) |
history : fs-history? |
cross-copies? : any/c |
Retrieves the next elder history object preceding history.
If cross-copies? is not #f, the history chain is
followed across copy events.
When fs-history-prev is called for the first time on a return value of fs-node-history, it may return an object equivalent to the one that was passed in, in case that object itself represents an interesting history event.
Retrieves the revision number and the path of the given
history event.
