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);
}
