% man ieee1284_read_status
The nAck pin is often able to trigger interrupts on the
host machine. With operating system help these interrupts
may be visible to the application via the selectable_fd
member of the parport structure.
Under Linux, the conditions are that the parallel port
driver knows which interrupt line to use and is using it,
and that the relevant /dev/parport device node is accessi-
ble and backed by a device driver.
Look in parport.h, I do not see selectable_fd member of the in struct parport.
