I had the same problem with several applications. However, I solved it with
a linked list. A linked list makes _one_ handle. When you want to "pass"
your data to a function, you simply use (or pass) the handle to the block
of memory and the offset to the specific data you want your function to use.

What's nice about using a linked list approach is that: 1) You don't have
to know in advance how much data you need -- you can add/substract memory
as you need on the fly; 2) You don't have to move memory around -- which
takes time; 3) You only have one handle and one offset to find any specific

Check out the linked list on my web site.
