No, you are not. I wasn't sure if the code is complete.

I'm not sure if it could help, try to add a call back function to your
TCPConnection_start function 

struct dataname 
{
  int length;
  char bytes[MAX_NAME_SIZE];
};


static void my_tcp_err(void *arg, err_t err)
{
  struct dataname * dataname;
  dataname = (struct dataname*)arg;
        printf("\r\n Error occured");
  mem_free(dataname);
}
