IDirect3DDevice9::GetVertexShader method

Retrieves the currently set vertex shader.

Syntax


HRESULT GetVertexShader(
  [out, retval]  IDirect3DVertexShader9 **ppShader
);

Parameters

ppShader [out, retval]

Type: IDirect3DVertexShader9**

Pointer to a vertex shader interface.

Return value

Type: HRESULT

If the method succeeds, the return value is D3D_OK. If ppShader is invalid, D3DERR_INVALIDCALL is returned.

Remarks

Typically, methods that return state will not work on a device that is created using D3DCREATE_PUREDEVICE. This method however, will work even on a pure device because it returns an interface.

Requirements

Header

D3D9.h

Library

D3D9.lib
