obtaining a pointer to a pointer for nlffi

I need a char ** for the arg to a function.

So I created a char * to actually hold the string

stringList = C.alloc C.T.uchar (Word.fromInt (size name + 1))

Then I tried the obvious:

C.Ptr.|&| stringList

but I get an error:

   operator domain: ('Z,'Y) C.obj
   operand:         (C.uchar,'X) C.obj C.ptr
   in expression:
     C.Ptr.|&| stringList

The error message makes perfect sense, it's trying to create a ptr to  
an obj, but I already have a ptr, not an obj.  Unfortunately I can't  
figure out how to make it take the ptr of a ptr.

Help...

Thanks

Brian
