CMediaSample::SetPointer (Windows Embedded CE 6.0)
1/6/2010
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).

| Windows Embedded CE | Windows CE 2.12 and later |
| Note | Microsoft DirectShow applications and DirectShow filters have different include file and Library requirements For more information, see Setting Up the Build Environment, Version 2.12 requires DXPAK 1.0 or later |
