+
+* Macro macro that obtains string name of type, using RTTI.
+
+* Returns demangled RTTI type name.
+
+* Examples
+
+  ```cpp
+  struct Base { virtual void foo() {} };
+  struct Derived : Base {};
+
+  Base* ptr = new Derived();
+  NAMEOF_TYPE_RTTI(ptr)  -> "Base *"
+  NAMEOF_TYPE_RTTI(*ptr) -> "Derived"
