IWMWriterSink::IsRealTime method (wmsdkidl.h)

[The feature associated with this page, Windows Media Format 11 SDK, is a legacy feature. It has been superseded by Source Reader and Sink Writer. Source Reader and Sink Writer have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Source Reader and Sink Writer instead of Windows Media Format 11 SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The IsRealTime is called by the writer to determine whether the sink needs data units to be delivered in real time. It is up to you to decide whether your custom sink requires real-time delivery.

Syntax

HRESULT IsRealTime(
  [out] BOOL *pfRealTime
);

Parameters

[out] pfRealTime

Pointer to a Boolean value that is True if the sink requires real time data unit delivery.
