CMediaSample::SetPointer (Compact 2013)

Sets the buffer pointer and length.

Syntax

SetPointer(
  BYTE* ptr,
  LONG cBytes 
);

Parameters

  • ptr
    Pointer to a buffer.
  • cBytes
    Length of the buffer, in bytes.

Return Value

None.

Remarks

Allocators that require variable-sized pointers or pointers into data that has already been read use this member function.

This is available only through a CMediaSample class, not an IMediaSample interface, so only the filter that owns the allocator knows how to access this member function (not any filter or pin that is passed the object's IMediaSample interface pointer).

Requirements

Header

dshow.h,
Streams.h

Library

ole32.lib,
Ole32auth.lib,
Strmbase.lib,
Strmiids.lib,
uuid.lib
