 pengine_property(?Pengine, ?Property) is nondet
True when Property is a property of the given Pengine. Enumerates all pengines that are known to the calling Prolog process. Defined properties are:
self(ID)
Identifier of the pengine. This is the same as the first argument, and can be used to enumerate all known pengines.
alias(Name)
Name is the alias name of the pengine, as provided through the alias option when creating the pengine.
thread(Thread)
If the pengine is a local pengine, Thread is the Prolog thread identifier of the pengine.
remote(Server)
If the pengine is remote, the URL of the server.
application(Application)
Pengine runs the given application
module(Module)
Temporary module used for running the Pengine.
destroy(Destroy)
Destroy is true if the pengines is destroyed automatically after completing the query.
parent(Queue)
Message queue to which the (local) pengine reports.
source(?SourceID, ?Source)
Source is the source code with the given SourceID. May be present if the setting debug_info is present.
detached(?Time)
Pengine was detached at Time.
