Errors that occur while accessing a repository are saved on a Microsoft® Repository error queue. A Repository error queue is a collection of REPOSERROR structures. Each thread of execution with an open Repository instance can access one active error queue at a time.
Use the IRepositoryErrorQueueHandler interface to create a Repository error queue, assign an error queue to a thread of execution, or retrieve an interface pointer to a thread's currently assigned error queue.
