@exe_child_of(son:exe, ancestor:exe)
returns true
if son
is a descendent of
ancestor
. Both argument must refer to live exe. If one of
them is not alive, false
value is returned.
An exe is considered as a child of itself. Thus,
@exe_child_of(ex, ex)
returns true if ex
is a live exe.
The child relation between the son
and the ancestor
is not necessarily direct: a process \(P\) that is spanned by a
loop triggered by a whenever in a group \(G\) is a child of \(G\) (in
pedantic terms, the child relation is the reflexive-transitive closure
of the relation defined by the function @exe_parent).
See also @exe_parent, the special variables $MYSELF
and
$THISOBJ
