But what if I have a class something like:
class port
{
int port_num;
public port (int i)
{
port_num = i;
}
public void open ()
{
OsOpenPort (i);
}
public void close ()
{
OsClosePort (i);
}
}
Assume that this class is accessing some hardware port via the OS, maybe a
serial port.
You would certainly like that port to be available after the application is
terminated.
How do I ensure that the close() method is called ?
It is unreasonable to expect that the application will always call the
close() method, especially if there is an error.
