memlog-entry

Arguments: index &key return log wait

Return one entry from the current or the specified memory log. Return nil if an entry was not obtained.

The index argument specifes the desired entry: 0 denotes the oldest entry; -1 denotes the most recent entry.

If log is specified, return an entry from that log.

If wait is specified, it determines how long to wait in order to acquire a log on the current 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).

The return argument may be :list, :vector, a list or a vector:

Note that each entry from a current and active log is fetched under a new lock. Thus two calls with the same index may not retrieve the same entry. Two calls with consecutive indices may return unrelated entries If consistent indexed access is desired, a copy of the current log must be made.
