示例1: ReceiveDataCallback

void DZeroCopyLoopbackDevice::ReceiveDataCallback()
	{
	// Copy buffer from send queue (it's like our receive hardware) to receive queue
	DCommsBuf* srcBuf = iSendQueue.HeadBuffer();
	if(!iReceiveQueue.IsFull() && !iSendQueue.IsEmpty())
		{
		// Alloc a new buffer in to which we will copy the received (sent) buffer (mimicking DMA in the non zerocopy case)
		DCommsBuf newBuf;
		TInt result = iLdd->Pond().Alloc(newBuf);
		if(result == KErrNone)
			{
			// Copy our buffer and set the new buffer's properties
			TInt srcPayloadLength = srcBuf->Length();
			newBuf.SetOffset(0);
			newBuf.SetLength(srcPayloadLength);

			// Do the copy
			TUint8* srcPayloadPtr = srcBuf->Ptr();
			TUint8* destPayloadPtr = newBuf.Ptr();
			memcpy(destPayloadPtr, srcPayloadPtr, srcPayloadLength);

			// Put the new buffer in the receive queue
			DCommsBuf* destBuf = iReceiveQueue.TailBuffer();
			*destBuf = newBuf;
			iReceiveQueue.Push();

			// Drop the incoming buffer
			srcBuf->Free();

			// Step the queue
			iSendQueue.Pop();
			}

		// We can now complete any outstanding request for received data - if indeed we managed to alloc a receive buffer
		if(iPendingRead && !iReceiveQueue.IsEmpty())
			{
			iPendingRead = FALSE;
			
			// Tell LDD we're done
			iLdd->ReceiveDataComplete(KErrNone);
			}
		}
