I have not looked into it but there would be use for a function similar to

what this one sounds like.



What I would like to see is to be able to allocate a small amount (but I

can't see why this should be forced) of memory for which I can later on

retrieve the address (I identify some sort of identifier).  This would

have little use for applications but simplify writing certain API calls

I have written a lot.  The 'handle' allows any number of independant

pieces of code to all have their own per thread data.
