Description

The generic function destroy-dependent-object is part of a mechanism for destroying objects when a pinboard-layout is destroyed.

Objects may be registered for destruction by calling record-dependent-object and unregistered by calling unrecord-dependent-object.

The predefined destroy-dependent-object method specializing on cl:cons expects a list where the car is a function and the cdr are its arguments. It applies the function to the arguments. The predefined method specializing on mp:process calls mp:process-terminate on the process object .
