You can use the ShutdownServer method and pass the DBSC_SHUTDOWN_CLEANLY type to cancel an active synchronization. The dbmlsync
server attempts to cancel the synchronization before shutting down. This task is the equivalent of canceling a synchronization
using the DBTools interface.
A connection must be established to the server before this method can be used. This method cannot be used if the client has
disconnected from the server since the Sync method was called.
