IDirect3DDevice8::GetStreamSource

Retrieves a vertex buffer bound to the specified data stream.

HRESULT GetStreamSource(
   UINT StreamNumber
   IDirect3DVertexBuffer8** 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 IDirect3DVertexBuffer8 interface, representing the returned vertex buffer bound to the specified data stream.

pStride

[in, out] Pointer to a returned stride of the component, in bytes. See Remarks.

Return Values

If the method succeeds, the return value is D3D_OK.

If the method fails, the return value can be D3DERR_INVALIDCALL.

Remarks

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

Note  Calling this method will increase the internal reference count on the IDirect3DVertexBuffer8 interface. Failure to call IUnknown::Release when finished using this IDirect3DVertexBuffer8 interface results in a memory leak.

Requirements

  Header: Declared in D3d8.h.
  Import Library: Use D3d8.lib.
