IWMWriter::AllocateSample

The AllocateSample method allocates a buffer that can be used to provide samples to the writer. This is optional; any INSSBuffer object can be used for this purpose.

Syntax

HRESULT AllocateSample(
  DWORD  dwSampleSize,
  INSSBuffer**  ppSample
);

Parameters

  dwSampleSize

[in]  Double word containing the sample size.

  ppSample

[out]  If the method succeeds, returns a pointer to a pointer to an INSSBuffer object containing the sample.

Return Values

If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code.

Remarks

This method is optional; developers are free to create and allocate their own buffer class.
