IGuideData::GetScheduleEntryIDs Method
The GetScheduleEntryIDs method returns a list of unique identifiers for all of the schedule entries contained in all transport streams.
Syntax
HRESULT GetScheduleEntryIDs(
[out] IEnumVARIANT **ppEnumScheduleEntries
);
Parameters
- ppEnumScheduleEntries [out]
Receives a pointer to the IEnumVARIANT interface. Use this interface to enumerate the collection. The caller must release the interface.
Return Value
The method returns an HRESULT. Possible values include those in the following table.
| Return code | Description |
|---|---|
S_OK |
The method succeeded. |
Remarks
The method fails if the TIF has not received the schedule information from the PSI tables in the transport stream. The client should implement the IGuideDataEvent interface and wait for the IGuideDataEvent::ScheduleEntryChanged event to be fired.
Each VARIANT type in the collection contains a BSTR that uniquely identifies one schedule entry within the multiplex. To get more information about the schedule entry, pass the VARIANT to the IGuideData::GetScheduleEntryProperties method.
The returned IEnumVARIANT interface is not thread safe. Clients should not call methods on the interface from more than one thread.
