Gck.Enumerator.next

### Method

# Gck Enumeratornext

#### Declaration [src]

    GckObject*
    gck_enumerator_next (
      GckEnumerator* self,
      GCancellable* cancellable,
      GError** error
    )

#### Description [src]

Get the next object in the enumerator, or `NULL` if there are no more objects.

`NULL` is also returned if the function fails. Use the `error` to determine whether a failure occurred or not.

#### Parameters

`cancellable`

  Type: `GCancellable`

  A `GCancellable` or `NULL`.

  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: `GckObject`

The next object, which must be released using g_object_unref, or `NULL`.

The caller of the method takes ownership of the returned data, and is responsible for freeing it.
The return value can be `NULL`.
