-SYNOPSIS
- int <lfun> (int refcount)
- int <closure>(int ref, object ob)
-
-DESCRIPTION
- The hook H_CLEAN_UP defines a lfun or a closure used to clean
- up an object. In older drivers this was hardwired to the lfun
- clean_up().
-
- The function is applied by the driver when an object hasn't been
- used for a long time, to give it a possibility to
- self-destruct. The refcount <ref> passed as argument will be 0 for
- clone objects, 1 for a simple loaded object, and greater when
- the object is cloned or inherited by some existing object. It
- is recommended not to self_destruct the object when the
- reference count is greater than one.
-
- By convention, a refcount < 0 is used if some other object
- asks the called object to clean_up.
-
- If the function is a closure, the second argument <ob> is the
- object to clean up.
-
- If the hook specifies a non-existing lfun, or if the call
- returns 0, no further attempt to clean up this object will be done.
-
- Returning a non-zero value is only recommended when the reason
- why the object can't self-destruct is likely to vanish without
- the object being touched, that is, when no local function is
- called in it, (and in compat mode also when the object is not
- being moved around).
-
- A typical mud configuration defines the time to wait for
- clean_up() so long that you can assert reset() has been
- called since the object has been touched last time.
-
-EXAMPLES
- A clone of /std/drink defines clean_up() to self-destruct if
- it is empty, not carried a living being and not touched for
- a long time.
-
- A room that inherits /std/room defines clean_up() to
- self-destruct if it is neither inherited nor used as a
- blueprint, is empty and was not entered for a long time.
-
-HISTORY
- Before 3.2.1, the function was hardwired to the lfun clean_up().
