IErrorLog

The IErrorLog interface is an abstraction for an "error log" that is used to communicate detailed error information between a client and an object. The caller of the single interface member, AddError, simply "logs" an error where the error is an EXCEPINFO structure attached to a specific property. The implementor of the interface is responsible for handling the error in whatever way it desires.

IErrorLog is used in the protocol between a client that implements IPropertyBag and an object that implements IPersistPropertyBag.
