#include <ieee1284.h>
void ieee1284_release (struct parport *port);
This function undoes the effect of ieee1284_claim(3) by releasing the
port for use by other drivers. It is good practice to release the port
whenever convenient. If it is never convenient to do so, the F1284_EXCL
flag should be specified at initialization.
