NAME

dce_db_iter_next_by_uuid - During iteration, returns the next key from a backing store indexed by UUID

SYNOPSIS

#include <dce/dce.h>
#include <dce/dbif.h>

void dce_db_iter_next_by_uuid(
    dce_db_handle_t handle,
    uuid_t **key,
    error_status_t *status);

PARAMETERS

Input

handle: A handle, returned from dce_db_open(), that identifies the backing store being used.

Output

key: The UUID that is the key to the item in the backing store.
status: A pointer to the completion status. On successful completion, the routine returns error_status_ok. Otherwise, it returns an error.

DESCRIPTION

The dce_db_iter_next_by_uuid() routine retrieves the next key from the backing store that is identified by the handle parameter. An iterator established by the dce_db_iter_start() routine maintains the identity of the current key. Use the dce_db_fetch_by_uuid() routine to retrieve the actual data.

This iteration routine is the same as dce_db_iter_next(), except that it only works with backing stores indexed by UUID, and returns an error if the backing store index is the wrong type.

The iteration routine returns a pointer to a private space associated with the handle. Each call to the iteration routine reuses the space, instead of using allocated space.

ERRORS

error_status_ok: The call was successful.
