propputref attribute

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


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

Parameters

optional-property-attributes

Zero or more property attributes.

return-type

The type of the data returned by the remote procedure.

function-name

The name of the remote procedure.

parameters

Zero or more parameters to the remote procedure.

Remarks

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

INVOKE_PROPERTYPUTREF

Examples

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