Determines whether r represents an entity with a parent.

The result is determined as follows:

• If r represents the global namespace, returns false.
• Otherwise, if r represents an entity that has "C" language linkage, returns false.
• Otherwise, if r represents an entity that has a language linkage other than "C++" language linkage, returns an implementation-defined value.
• Otherwise, if r represents a type that is neither class nor enumeration type, returns false.
• Otherwise, if r represents an entity or direct base class relationship, returns true.
• Otherwise, returns false.

Parameters
