Releasing temporary variables created with IDL_MakeTempArray() [message #90709]

Dear Folks,

A DLM I've written in C uses
IDL_MakeTempArray()
to allocate an array, let's call it ARR, that gets passed back to IDL.
I'd like to release that temporary variable in IDL without having
to call a routine in the DLM that invokes IDL_Deltmp() .

1. Can I just do something like
IDL> ARR = 0
to release the temporary variable? Or is there another IDL-based method?

2. At a deeper level, say that I've created a pointer to ARR with
IDL> PARR = ptr_new(ARR, /no_copy)
Will freeing the pointer with
IDL> ptr_free, PARR
also release the temporary variable?

3. Is there a way to see how many temporary variables I have checked
out? Is there a limit to that number? What's the limit?

Many thanks,

David
