request deallocation" vi

[Pandiyan]

hi  i have some doubt,

 i have reentrant vi , i call it by "open vi ref function" at 5 no of  times,so its makes 5 clone vi.in ram its make individual space for each clone

1.suppose i close the clone vi but now top level vi isnot closed ,in this case labview clear the memory space of old clone.

vi or still retain in ram?

2.in this case is request deallocation" vi  useful suppose old clone vi mem retain in ram?

if its how can i impement by request deallocation" vi

Request deallocation only is effective when the VI is removed from memory. This normally will happen when the ref to the sub-VI is closed.
