Iterator — unified iterator

struct

The iterator keeps the direction and the last position for access to the internal library tables/lists.

void
scols_free_iter (struct libscols_iter *itr);

Deallocates the iterator.

itr

iterator pointer

int
scols_iter_get_direction (struct libscols_iter *itr);

itr

iterator pointer

SCOLS_INTER_{FOR,BACK}WARD

struct libscols_iter *
scols_new_iter (int direction);

direction

SCOLS_INTER_{FOR,BACK}WARD direction

newly allocated generic libmount iterator.

void
scols_reset_iter (struct libscols_iter *itr,
                  int direction);

Resets the iterator.

itr	iterator pointer
direction	SCOLS_INTER_{FOR,BACK}WARD or -1 to keep the direction unchanged
