Detailed Description

A dummy sink class that can be added to a IWMWriter session mainly to test that the writer can write.

Nothing is done with the data it is given. It is designed to be allocated on the stack, AddRef and Release do nothing.

Constructor & Destructor Documentation

NullSink::NullSink ( BOOL realTime )

Constructs either a normal or realtime NullSink instance

Parameters:

realTime Whether the sink needs realtime samples for writing or not

ULONG WINAPI NullSink::AddRef ( )

Does nothing, the class is meant to be allocated on the stack

HRESULT WINAPI NullSink::AllocateDataUnit	(	DWORD	dataSize,
		INSSBuffer **	ppBuffer
	)

Creates a new buffer of the requested size

Parameters:

	dataSize	Initial size of the memory buffer
[out]	ppBuffer	Pointer that receives the interface pointer of the wrapper around the new buffer

HRESULT WINAPI NullSink::IsRealTime ( BOOL * pRealTime )

Called by the writer to determine if the sink requires realtime packets

Parameters:

pRealTime Pointer to a bool that receives the realtime value given to the constructor

HRESULT WINAPI NullSink::OnDataUnit ( INSSBuffer * pData )

Does nothing, called when their is a new data to write to the stream

Parameters:

pData Buffer containing data to write

HRESULT WINAPI NullSink::OnEndWriting ( )

Does nothing, called when all writing has finishe

HRESULT WINAPI NullSink::OnHeader ( INSSBuffer * pHeader )

Does nothing, called when their is a new stream header to write

Parameters:

pHeader Buffer containing a new header to write

ULONG WINAPI NullSink::Release ( )

Does nothing, the class is meant to be allocated on the stack
