The only thing I would really change is to add functions which include
the opening and closing of the port. With other words, the application
only calls something like gpio_pin_write (Name, Pin, value) or
gpio_pin_write (Pin, value) and gpio_pin_write opens and closes the
device. Plus a function to set the device name to be used for all later
calls.
