Question

I have a problem with a function.
I want to send bytes to through a tcp socket.
However I have not figured out how to do that as I get warnings that my types don’t machs
here’s the code:
This is in the application viewcontroller:

-(IBAction) sendClicked:(id)sender{
    Byte sendBuffer[10];
    sendBuffer[0]=1;
    sendBuffer[1]=0;
    sendBuffer[2]=1;
    sendBuffer[3]=0;
    sendBuffer[4]=1;
    sendBuffer[5]=0;
    sendBuffer[6]=0;
    sendBuffer[7]=1;
    sendBuffer[8]=0;
    sendBuffer[9]=1;

if(tcp) [tcp sendData: *sendBuffer]

}

and this is in the tcp.m file:

-(void) sendData: (Byte*) sendBytes {
    NSData *data;
        memcpy(data,sendBytes,200);
        [socket writeData: data withTimeout:-1 tag:0];
    sendBuffer=nil;
}

Should I use NSMutablearrays instead?I admit, I am a beginner. Hope someone can help me.

The problem is that *sendBuffer refers to the first Bytein the sendBuffer array. Try this:

if (tcp) [tcp sendData: sendBuffer];

Oh, and you’re missing a semicolon.
