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