I0

The zeroth interface ID. (Mandatory)

I1

The first interface ID. (Optional)

I2

The second interface ID. (Optional)

I3

The third interface ID. (Optional)

I4

The fourth interface ID. (Optional)

I5

The fifth interface ID. (Optional)

I6

The sixth interface ID. (Optional)

I7

The seventh interface ID. (Optional)

I8

The eigth interface ID. (Optional)

I9

The ninth interface ID. (Optional)

flags

Configuration flags for the class. One or more RuntimeClassType enumerations that are specified in a RuntimeClassFlags structure.

Derives from the list of specified interfaces and implements helper templates for QueryInterface and GetIid.

Each I0 through I9 interface parameter must derive from either IUnknown, IInspectable, or the ChainInterfaces template. The flags parameter determines whether support is generated for IUnknown or IInspectable.
