Method

TrackerSparqlCursornext

Declaration [src]

gboolean
tracker_sparql_cursor_next (
  TrackerSparqlCursor* cursor,
  GCancellable* cancellable,
  GError** error
)

Description [src]

Iterates the cursor to the next result.

If the cursor was not started, it will point to the first result after this call. This operation is completely synchronous and it may block, see tracker_sparql_cursor_next_async() for an asynchronous variant.

Parameters

cancellable

Type: GCancellable

Optional GCancellable.

The argument can be NULL.

The data is owned by the caller of the method.

error

Type: GError **

The return location for a recoverable error.

The argument can be NULL.

If the return location is not NULL, then you must initialize it to a NULL GError*.

The argument will be left initialized to NULL by the method if there are no errors.

In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.

Return value

Type: gboolean

FALSE if there are no more results or if an error is found, otherwise TRUE.
