I got a variety of solutions, but perhaps I didn't state the problem clearly.
The form ((StructName *)Something)->x=100 works. 
However, the format I need is this type:

TopLevel->Secondary->Something->x=100;

i.e. I can't do the casting in the middle of the dereference. It won't let
me no matter which way I do it. Toplevel contains a pointer to
Secondary, which contains Something. Something initially points to a
void *. 
I want to be able to make it point to, say a struct StructName which has 
as one of its elements x, and be able to change that element. However,
if I allocate space for Something by casting to StructName, it still has
problems getting to x. 

Hope this makes the problem clearer.
