There's no way to recover the type from a void*.



What the reason behind it..???

The void* type can hold a pointer of any data type, and even if the data
contains some sort of self-identifying tag, it could be a spurious
occurrence of that tag. So the only reliable way to tell what a void*
points to is to remember it yourself. Things are much different in .NET
where everything derives from System.Object, and you can recover type
information when you have an Object reference.
