deallocating ptrs [message #44353]

Hi,
I am reading an HDF, and have a template created with the HDF_browser.
The template is a structure that has over 200 pointers deeply nested in
several labrynthical "subnested structure arrays of structure ptr array
structures".
:)

So, I tried to deallocate this monster with a heap_free call, and it doesn't
get
deallocated. (IDL 6.1)
In fact I have for the moment been reduced to a heap_gc call, which seems
inelegant.

So why doesn't heap_free free the heap? It looks like is isn't even trying.
It goes from 238 to 164 ptrs.

Anyone have a nice generic deallocating routine to crawl down the structure.
I actually have an old routine that prints out a structure nicely, that
recursively
steps through each element. It could be modified to test each element and
deallocate it if it is a ptr, but there has to be a routine that already
does that.

Cheers,
bob
