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 CMediaSampleclass, not an IMediaSampleinterface, 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 IMediaSampleinterface pointer).

Windows Embedded CE Windows CE 2.12 and later
Windows Mobile Windows Mobile Version 5.0 and later
Note Microsoft DirectShow applications and DirectShow filters have different include file and Library requirements
