// The following are definitions for the Flags field in the context handle.
//
// ELF_LOG_HANDLE_INVALID is used to indicate that the handle is no
//                        longer valid - i.e. the contents of the file
//                        or the file itself have changed. It is used for
//                        READs to cause the reader to "resync".
//
// ELF_LOG_HANDLE_BACKUP_LOG indicates that this was created with the
//                        OpenBackupEventlog API and is not an active log.
//                        This means we do some additional work at close time
//                        and we disallow clear, backup, write and
//                        ChangeNotify operations.
//
// ELF_LOG_HANDLE_REMOTE_HANDLE indicates that this handle was created via
//                        a remote RPC call.  This handle cannot be used for
//                        ElfChangeNotify
//
// ELF_LOG_HANDLE_GENERATE_ON_CLOSE indicates that NtCloseAuditAlarm must
//                        be called when this handle is closed.  This flag
//                        is set when an audit is generated on open.
