Syntax


HRESULT SetAllocateForPostView(
  [in] WORD wStreamNumber,
  [in] BOOL fAllocate
);

Parameters

wStreamNumber [in]

WORD containing the stream number.

fAllocate [in]

Boolean value. Set to True if the application allocates buffers, and False if this is left to the reader.

Return value

The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.

Return codeDescription
S_OK

The method succeeded.

NS_E_INVALID_STREAM

The stream number specified by wStreamNumber is not valid.

E_OUTOFMEMORY

The method was unable to create an internal structure.

 

Remarks

The application can provide buffers for any of the outputs, rather than use those allocated by the reader. For example, some applications can allocate Microsoft DirectDraw® buffers.

The actual allocation of buffers is handled by the IWMReaderCallbackAdvanced interface.
