IEEE1284_REF(3) Functions IEEE1284_REF(3)
NAME
ieee1284_ref, ieee1284_unref - modify a port's reference count
SYNOPSIS
#include <ieee1284.h>
int ieee1284_ref(struct parport *port);
int ieee1284_unref(struct parport *port);
DESCRIPTION
If you want to free the port list from ieee1284_find_ports but open one
of the ports later on, you will need to prevent it from being destroyed
in ieee1284_free_ports. Each port has a reference count, and you can
use ieee1284_ref to increment it and ieee1284_unref to decrement it.
If you use ieee1284_ref at any stage, you must later call
ieee1284_unref to relinquish the extra reference. If you do not do
this, the resources associated with the port will not be cleaned up.
If you have not previously used ieee1284_ref on a port, you must not
use ieee1284_unref on it.
RETURN VALUE
These functions return the number of references held after the
increment or decrement.
