31 | * type of protocol is used over the connection. The high bit |
32 | * (0x80) of the operation type field is used to indicate whether |

36 | * communicates the result of the corresponding request. A zero |
37 | * result value means the operation completed successfully. Any |
38 | * other value indicates an error; in this case, the payload of the |
39 | * response message (if any) is ignored. The result byte must be |
40 | * zero in the header for a request message. |
