Apologies for the formatting of these replies, I'm at work with Lotus 
Notes.

PNI (Parrot Native Interface) is for writing native extensions in C.
So, what I meant is you can write a method for stashing a raw pointer with
the API today (probably using char *). I'm not sure if it is your 
preferred method,
and I understand your wariness of bytecode in this case. I was 1/2 asleep
this morning on IRC when I suggested it, not understanding the case
you were dealing with.

You can see samples that Dan has played with such as ncurses somewhere
in the examples area. (I'm still not saying you don't need API added to 
extend.h
though, but I'd have to be very clear on what you are asking for...)

The function is a C function.  And yes it is a custom PMC which I have 
already created.

Dan pointed out the unmanagedstruct.pmc which but I fail to see how 
that would help me, I think we need an external API for stashing raw 
pointers.

(I don't know what PNI is, but I assume it is to execute bytecode from 
C and I do not want to do that).
