Thanks for the help guys, got that problem fixed. I'm hoping you can help
me with one more thing with IDL pointers.
When we do something like:

foo_ptr = ptr_new(foo)

foo_ptr points to a memory location in the heap memory that contains
foo's value, correct? So, am I safe to assume it copys whatever the value of
foo is into the heap variable that foo_ptr is pointing too?
And, if we do:

bar_ptr = ptr_new(bar, /no_copy)

bar_ptr will now just point to the memory location where bar is stored
(not copy it to a heap location)? We can then update the bar, or the
components of bar(if bar is a structure) by dereferencing bar_ptr, right?
For example:

*bar_ptr.name = 'Geoff'

Thanks for everyone's help. I've only worked with pointers in
C/C++ before, and I'm getting the impression that these don't work exactly
the same way. =)
