nn::Result ReceiveFrom(
     const EndpointDescriptor & endpointDesc,
     void * pBuffer,
     size_t * pReceivedSize,
     u16 * pSrcNodeId,
     size_t bufferSize,
     bit8 option = 0x00
);

	Name	Description
in	endpointDesc	Descriptor indicating the endpoint to use. The port and sending source must be attached in advance using the Attach function.
out	pBuffer	Received data storage location. Specify a buffer aligned to 4 bytes.
out	pReceivedSize	Size of the received data. The UDS maximum received data size is UDS_PACKET_PAYLOAD_MAX_SIZE bytes.
out	pSrcNodeId	Sending source node ID.
in	bufferSize	Size of the receive buffer (pBuffer).
in	option	Receive options. Specifying NO_WAIT here will cause the function to return immediately, even if no data has been received. If not specified, the function will not return until either it receives data or an error occurs.
