Iterator

Iterator — unified iterator

Synopsis

struct              libmnt_iter;
void                mnt_free_iter                       (struct libmnt_iter *itr);
int                 mnt_iter_get_direction              (struct libmnt_iter *itr);
struct libmnt_iter * mnt_new_iter                       (int direction);
void                mnt_reset_iter                      (struct libmnt_iter *itr,
                                                         int direction);

Description

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

Details

struct libmnt_iter

struct libmnt_iter;

Generic iterator (stores state about lists)

mnt_free_iter ()

void                mnt_free_iter                       (struct libmnt_iter *itr);

Deallocates iterator.

itr :

iterator pointer

mnt_iter_get_direction ()

int                 mnt_iter_get_direction              (struct libmnt_iter *itr);

`itr` :	iterator pointer
Returns :	MNT_INTER_{FOR,BACK}WARD or negative number in case of error.

mnt_new_iter ()

struct libmnt_iter * mnt_new_iter                       (int direction);

`direction` :	MNT_INTER_{FOR,BACK}WARD direction
Returns :	newly allocated generic libmount iterator.

mnt_reset_iter ()

void                mnt_reset_iter                      (struct libmnt_iter *itr,
                                                         int direction);

Resets iterator.

`itr` :	iterator pointer
`direction` :	MNT_INTER_{FOR,BACK}WARD or -1 to keep the derection unchanged
