69 * All operation messages (both requests and responses) begin with
70 * a header that encodes the size of the message (header included).
71 * This header also contains a unique identifier, that associates a
72 * response message with its operation. The header contains an
73 * operation type field, whose interpretation is dependent on what
74 * type of protocol is used over the connection. The high bit
75 * (0x80) of the operation type field is used to indicate whether
76 * the message is a request (clear) or a response (set).
78 * Response messages include an additional result byte, which
79 * communicates the result of the corresponding request. A zero
80 * result value means the operation completed successfully. Any
81 * other value indicates an error; in this case, the payload of the
82 * response message (if any) is ignored. The result byte must be
83 * zero in the header for a request message.
85 * The wire format for all numeric fields in the header is little
86 * endian. Any operation-specific data begins immediately after the
