IDirect3DDevice9::GetVertexShader method (d3d9helper.h)

Retrieves the currently set vertex shader.

Syntax

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

Parameters

[out, retval] ppShader

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.
