Method

TsparqlSparqlCursornext_async

Declaration [src] 

void
tracker_sparql_cursor_next_async (
  TrackerSparqlCursor* cursor,
  GCancellable* cancellable,
  GAsyncReadyCallback callback,
  gpointer user_data
)

Description [src]

Iterates the cursor asyncronously to the next result.

If the cursor was not started, it will point to the first result after this operation completes.

In the period between this call and the corresponding tracker_sparql_cursor_next_finish() call, the other cursor methods should not be used, nor their results trusted. The cursor should only be iterated once at a time.

This method completes asynchronously. Use tracker_sparql_cursor_next_finish() inside the GAsyncReadyCallback to obtain the result of the operation.
