Gets details of the original event, if this event is an exception to a recurring event. The original event's ID and the URI of the event's XML are returned in `event_id` and `event_uri`, respectively.

If this event is not an exception to a recurring event, `event_id` and `event_uri` will be set to `NULL`. See `gdata_calendar_event_is_exception()` to determine more simply whether an event is an exception to a recurring event.

If both `event_id` and `event_uri` are `NULL`, this function is a no-op. Otherwise, they should both be freed with `g_free()`.

`self` : | a GDataCalendarEvent
`event_id` : | return location for the original event's ID, or `NULL`. [out callee-allocates][transfer full]
`event_uri` : | return location for the original event's URI, or `NULL`. [out callee-allocates][transfer full]

Since 0.3.0

### gdata_calendar_event_is_exception ()

    gboolean            gdata_calendar_event_is_exception   (GDataCalendarEvent *self);

Determines whether the event is an exception to a recurring event. If it is, details of the original event can be retrieved using `gdata_calendar_event_get_original_event_details()`.

`self` : | a GDataCalendarEvent
Returns : | `TRUE` if the event is an exception, `FALSE` otherwise

Since 0.3.0

### gdata_calendar_event_get_anyone_can_add_self ()

    gboolean            gdata_calendar_event_get_anyone_can_add_self
