I\'ve stored a pointer to a type_info object.
int MyVariable = 123;
const std::type_info* Datatype = &typeid(MyVariable);
I don't think such casting can be done. Suppose you could do "dynamic" casting like this at runtime (not to mean dynamic_cast). Then if you used the result of the cast to call a function the compiler could no longer do type checking on the parameters and you could invoke a function call that doesn't actually exist.
Therefore it's not possible for this to work.
