GPIO is a way to do pin assignments for a chip package at run-time. I
use it on embedded platforms all the time, but it isn't normally
available on a PC. There's a gpioctl(1) that should be able to set the
a pin for input or output, as those flags indicate, or programmatically
I guess it would be GPIO_PIN_INPUT or GPIO_PIN_OUTPUT in
/usr/include/sys/gpio.h but again, you need to have the hardware for it.
