memlog-start

Arguments: &key wait

Change the state of memory logging to :ready. If the current state was already :ready, return t. If the state was changed to :ready by this call, return :started.

If the wait argument is nil (or zero or negative), return nil if the state is not and cannot be immediately changed to :ready. If the wait argument is a positive integer N, wait up to N seconds. If the wait argument is any other non-nil value, wait indefinitely.

A delay may be caused by some other memlog operation in another thread.
