propputref

[propputref [,optional-property-attributes]] return-type func-name( parameters);

Example

interface InMyFace : IDispatch 
    {    
      [propget, helpstring("A meaningful comment."), id(1)]   
      HRESULT Method2([out, retval] InYourFace** ReturnVal); 
      [propputref, helpstring("Another meaningful comment."), id(1)]  
      HRESULT Method2([in] InYourFace* Point);
 

Remarks

The propputref attribute specifies a property-setting function that uses a reference instead of a value.

A function that has the propputref attribute must also have, as its last parameter, a pointer that has the in attribute.

The property must have the same name as the function. At most, one of propget, propput and propputref attributes can be specified for a function.

Flags
