This method retrieves a vertex buffer bound to the specified data stream.

Syntax 

HRESULT GetStreamSource(
  UINT 
StreamNumber,
  IDirect3DMobileVertexBuffer** 
ppStreamData,
  UINT* 
pStride
);

Parameters

StreamNumber

[in] Specifies the data stream, in the range from 0 to the maximum number of streams - 1.

ppStreamData

[in, out] Address of a pointer to an IDirect3DMobileVertexBufferinterface that represents the returned vertex buffer bound to the specified data stream.

pStride

[in, out] Pointer to a returned stride of the component, in bytes. For more information, see Remarks.

Return Value

If the method succeeds, the return value is D3DM_OK (see D3DM Values).

If the method fails, the return value can be D3DMERR_INVALIDCALL (see D3DMERR Values).

Remarks

A stream is defined as a uniform array of component data, in which each component consists of one or more elements that represent a single entity such as position, normal, color, and so on.

Calling this method will increase the internal reference count on the IDirect3DMobileVertexBufferinterface. Failure to call IUnknown::Releasewhen finished using this IDirect3DMobileVertexBufferinterface results in a memory leak.

Requirements

Header d3dm.h
Library D3dm.lib, D3dmguid.lib
Windows Embedded CE Windows CE 5.0 and later
Windows Mobile Windows Mobile Version 5.0 and later
