Returns the type of an event handler for the event ev generated by the particular COM object/type obj/type. The return type of all COM event handlers is void.

See also com-events for dealing with a COM object that has an ambiguous class.

Registers f as event handler for the event ev when generated by obj. The type of argument supplied tof depends on the event; the result of f is always discarded.

See also com-events for dealing with a COM object that has an ambiguous class.
