}

ERPC defines a krpc object

func NewERPC

func NewERPC() (*ERPC, error)

NewERPC returns a new ERPC object

func (*ERPC) Close

func (k *ERPC) Close() error

	// contains a slice header
	Data [ERPCDefaultDataSize]byte
}

Request defines a EPRC request

func NewERPCRequest

func NewERPCRequest(op uint8) *Request

NewERPCRequest returns a new eRPC request with a data section of the provided size
