2.2.6 Common Error Codes

Unless otherwise specified, the methods of the Windows Remote Registry Protocol MUST return 0 to indicate success and a nonzero implementation-specific value to indicate failure in the error_status_t return code of the response. All failure values MUST be treated as equivalent for protocol purposes and SHOULD simply be passed back to the invoking application.

Any implementation SHOULD return one of the following error codes.
