custom (C++)

Defines metadata for an object in the type library.

[ custom(
   uuid, 
   value
) ];

Parameters

  • uuid
    A unique ID.

  • value
    A value that can be put into a variant.

Remarks

The custom C++ attribute will cause information to be placed into the type library. You will need a tool that reads the custom value from type library.

The custom attribute has the same functionality as the custom MIDL attribute.
