memlog-state

Arguments: &key log wait

Return the state of memory logging.

If the log argument is specified, return the state of the specified log.

If the wait argument is specified, it determines how long to wait in order to gain access to the log (nil or 0 means do not wait, a positive number means wait that number of seconds, any other non-nil value means wait as long as necessary).

If memory logging is disabled, return nil.

Otherwise return 5 values: the current state keyword (:stopped or :ready) and 4 numbers which indicate entries, skipped, size, width.

The current memory log may be in other intermediate states but these exist only while the log is locked. Since memlog-state must acquire a lock to obtain a consistent snapshot, it can only report on the two stable unlocked states.
