# _com_ptr_t::Detach
**Microsoft Specific**  
  
 Extracts and returns the encapsulated interface pointer.  
  
## Syntax  
  
```  
  
Interface* Detach( ) throw( );  
  
```  
  
## Remarks  
 Extracts and returns the encapsulated interface pointer, and then clears the encapsulated pointer storage to **NULL**. This removes the interface pointer from encapsulation. It is up to you to call **Release** on the returned interface pointer.  
  
 **END Microsoft Specific**
