IAMMediaTypeSample::SetPointer method (amstream.h)

[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

Note  This interface is deprecated. New applications should not use it.
 
The SetPointer method sets the pointer to the media sample's memory buffer.

Syntax

HRESULT SetPointer(
  [in] BYTE *pBuffer,
  [in] long lSize
);

Parameters

[in] pBuffer

Pointer to a memory buffer allocated by the caller, or NULL.

[in] lSize

Size of the buffer, in bytes.

Return value

Returns one of the following values.

Return code Description
E_OUTOFMEMORY
Insufficient memory.

Remarks

If the value of the pBuffer parameter is NULL, the method allocates a memory block, with a size in bytes equal to the value of the lSize parameter. There is no guarantee that the memory has been initialized.
