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.
