Pointers

[Jedhi]

I was just wondering what you do in C# when you do not have any pointers. How would you for example do this in C# ?

 

byte *pData, byte length

byte ix = 0

static byte buffer[100];

 

for (int i=0;i<length;i++)

buffer[ix++] = pData;

You could just use arrays.

 

private void CopyArray(byte[] pData)
{
byte ix = 0;
byte[] buffer = new byte[100];

for (int i=0;ibuffer[ix++] = pData[i];
}

 

any reason why you need pointers? If so you can mark the code as being unsafe and pointers can be used.

I have some problems with callback function. Would you look through the code and correct the errors and send me back the source ?

[PlausiblyDamp]

what callback function?

In short term when clicked on the button buttonClick is activated. You send a broadcast to all the nodes by passing the parameters to the function SendData, afterwards it return. And call ActivateAlllNodeswhere it call itself until max number of nodes has been received. I do not know it is easier to look through having all the project.

 

private void buttonClick(object sender, System.EventArgs e)

{

 

if (api.SendData(BROADCAST,command,2, ActivateAlllNodes)))

{

m_txtStatus.Text.Insert(1,"OKAY");

}

else

{

m_txtStatus.Text.Insert(1,"FAILING");

}

}

 

public virtual void ActivateAlllNodes(byte[] command)

{

byte nodeID = 0;

while (nodeID++ < MAX_NODES)

{

if (nodeIDisaccepted)

break;

}

if (nodeID > MAX_NODES)

{

m_txtStatus.Text.Insert(1,"FINISH");

}

else

{

api.SendData(nodeID, command, 2,ActivateAlllNodes);

}

}

 

public delegate void CompletedFunc(byte b);

 

public byte SendData(byte nodeID, byte[] pdata, byte dataLength, CompletedFunc cmplfunc)

{

byte byCompletedFunc = ( cmplfunc == NULL? 0: 0x03); and some other stuff here...

}
