NAME

dnstable_iter - iterate over a sequence of dnstable entries

CONTENTS

SYNOPSIS

#include <dnstable.h>

dnstable_res
dnstable_iter_next(struct dnstable_iter *it, struct dnstable_entry **ent);

dnstable_iter_destroy(struct dnstable_iter **it);

DESCRIPTION

The dnstable_iter interface is used to return a sequence of one or more dnstable entries. Once the caller obtains a dnstable_iter object, dnstable_iter_next() should be repeatedly called on it until there are no more entries to retrieve, at which point the iterator object must be freed by calling dnstable_iter_destroy().

RETURN VALUE

dnstable_iter_next() returns dnstable_res_success if an entry was successfully retrieved, in which case ent will point to a dnstable_entry object which must be freed by the caller using dnstable_entry_destroy(). dnstable_res_failure is returned if there are no more entries in the sequence.
