COM_INTERFACE_ENTRY_NOINTERFACE

  • Article

 

Returns E_NOINTERFACE and terminates COM map processing when the specified interface is queried for.

Syntax

COM_INTERFACE_ENTRY_NOINTERFACE( 
x
 )

Parameters

  • x
    [in] Text used to construct the interface identifier.

Remarks

You can use this macro to prevent an interface from being used in a particular case. For example, you can insert this macro into your COM map right before COM_INTERFACE_ENTRY_AGGREGATE_BLIND to prevent a query for the interface from being forwarded to the aggregate's inner unknown.

The interface IID will be constructed by appending x to IID_. For example, if x is IPersistStorage, the IID will be IID_IPersistStorage.

See COM_INTERFACE_ENTRY Macros for remarks about COM map entries.
