Item API quicky - _itemRelease()

I have found in some old code a _potential_ issue

// Put the value into element
elem = _itemPutNL( elem, (long) val );

later in the code

_itemRelease( elem );

Now will the reassign of elem be a problem to the garbage collector, ie will
it all be cleared up by _itemRelease() or do I need to add another variable
to do this.

Thanks

The usage given above seems consistent with the documentation and the
example given in the documentation. In fact, if you look at the example
given in the documentation for _itemPutNL(), you'll notice it does pretty
much what you're doing here.

Just had a look - that's correct so it must be OK.

I was just a little unsure as I am not very experienced with C - all of my C
programs have been related to various XBASE front ends
