#include <ieee1284.h>

int ieee1284_find_ports(struct parport_list *list, int flags);

There are no flags defined; use zero for this parameter.

E1284_OK

Success. list is filled in and must be destroyed using ieee1284_free_ports(3).

E1284_NOMEM

There is not enough memory available.

E1284_NOTIMPL

One or more of the supplied flags is not supported in this implementation.
