Reading SmallSockets

Right now I'm working with SmallSockets because I know it can do what I
need it to.  However, I'm a little bit confused as to what's going on
when reading from the BufferedSocket class.  I've looked at a couple of
sources, but none of them seem to get it exactly right.  Here's what I
have in the communication thread (connection is a BufferedSocket):

- (void)threadCommunicate:(id)dummy {
    NSAutoreleasePool    *apool=[[NSAutoreleasePool alloc] init];
    NSMutableData    *message,*segment;
    NSString        *strMessage;
    NS_DURING
        while(1) {
            NSAutoreleasePool    *apool=[[NSAutoreleasePool alloc] init];
            /*message = [connection readData:1];
            [message appendData:[connection readData:[connection
bufferLength]]];
            if(!message) break;
            strMessage = @"";
            while([message length]) {
                segment = [message getBytes:[message length]];
                //[segment increaseLengthBy:1];
                strMessage = [NSString stringWithUTF8String:[segment
bytes]];
            }*/
            message = [connection readData:[connection bufferLength]];
            if(!message) break;
            strMessage = [NSString stringWithUTF8String:[message bytes]];
            if(strMessage) {
                [owner receivedMessage:strMessage];
            }
            [apool release];
            if(![connection isConnected]) [owner gotDisconnected];
        }
    NS_HANDLER
        [owner gotDisconnected];
    NS_ENDHANDLER
    [apool release];
}

How did I come up with that?  Again, a combination of sources that I've
looked at.  My question is, what exactly is this doing?  Shouldn't it
suffice to go "message = [connection readData:[connection
bufferLength]]"?  As far as I know, that should return all the available
data.  However, I tried, and it doesn't.  And I have no clue how I would
handle exceptions such as failing to connect or being remotely
disconnected.  If anyone could point me in the right direction on these
issues, I'd really appreciate it.  Thanks!
