lockedp

Arguments: lock &optional force-memory-synch

Returns t if the lock is held by anyone, nil if it is free.

lock must be an instance of lockable-object or of a subclass of lockable-object, or an instance of excl::lockable-structure or of a structure class that inherits from excl::lockable-structure.

If the force-memory-synch argument is present and non-nil, a memory synchronization operation will be used to ensure that an out-of-date cached state is not erroneously consulted to determine the answer.

See multiprocessing.htm for general information on multiprocessing in Allegro CL.
