[LLVMdev] Problems with void*

[Reid Spencer]

No value can be stored in a void and a function returning void* points
to nowhere in particular. I think what you are really wanting to do here
is use an opaque type. The other alternative is to simply use sbyte*. 

Remember, this isn't C even though some of the names/ideas look
familiar.
