Microsoft Specific**

Encapsulates a raw interface pointer of this smart pointer's type.

Syntax

  
      void Attach(  
   Interface* pInterface   
) throw( );  
void Attach(  
   Interface* pInterface,  
   bool fAddRef   
) throw( );

Parameters

pInterface
A raw interface pointer.

fAddRef
If it is true, then AddRef is called. If it is false, the _com_ptr_t object takes ownership of the raw interface pointer without calling AddRef.

Remarks

  • Attach(  pInterface  ) AddRef is not called. The ownership of the interface is passed to this _com_ptr_t object. Release is called to decrement the reference count for the previously encapsulated pointer.

  • Attach(  pInterface ,  fAddRef  ) If fAddRef is true, AddRef is called to increment the reference count for the encapsulated interface pointer. If fAddRef is false, this _com_ptr_t object takes ownership of the raw interface pointer without calling AddRef. Release is called to decrement the reference count for the previously encapsulated pointer.
