Compares the underlying std::type_info objects.

1-2) Checks whether the underlying std::type_info objects refer to the same type.

3-6) Compares the underlying std::type_info objects as defined by an implementation-defined ordering. The comparison is done by type_info::before.

Parameters

Return value

1) true if the underlying std::type_info objects refer to the same type, false otherwise.

2) true if the underlying std::type_info objects refer not to the same type, false otherwise.

3-6) true if the types referred by the underlying std::type_info objects are ordered by corresponding order, false otherwise.
