ComPtrRefBase Class
Supports the WRL infrastructure and is not intended to be used directly from your code.
Syntax
template <typename T>
class ComPtrRefBase;
Parameters
T
A ComPtr<T> type or a type derived from it, not merely the interface represented by the ComPtr.
Remarks
Represents the base class for the ComPtrRef class.

ComPtrRefBase::operator IInspectable** Operator
Supports the WRL infrastructure and is not intended to be used directly from your code.
operator IInspectable**() const;
Remarks
Casts the current ptr_ data member to a pointer-to-a-pointer-to the IInspectable interface.
An error is emitted if the current ComPtrRefBase doesn't derive from IInspectable.
This cast is available only if __WRL_CLASSIC_COM__ is defined.
ComPtrRefBase::operator IUnknown** Operator
Supports the WRL infrastructure and is not intended to be used directly from your code.
operator IUnknown**() const;
Remarks
Casts the current ptr_ data member to a pointer-to-a-pointer-to the IUnknown interface.
An error is emitted if the current ComPtrRefBase doesn't derive from IUnknown.
ComPtrRefBase::ptr_
Supports the WRL infrastructure and is not intended to be used directly from your code.
T* ptr_;
Remarks
Pointer to the type specified by the current template parameter. ptr_ is the protected data member.
