+* @name IDirect3D9::CheckDepthStencilMatch
+* @implemented
+*
+* The function IDirect3D9Impl_CheckDepthStencilMatch checks if a specific =
combination
+* of a render target D3DFORMAT and a depth-stencil D3DFORMAT can be used w=
ith a specified
+* D3DFORMAT on the specified display adapter.
+*
+* @param LPDIRECT3D iface
+* Pointer to the IDirect3D object returned from Direct3DCreate9()
+*
+* @param UINT Adapter
+* Adapter index to get information about. D3DADAPTER_DEFAULT is the primar=
y display.
+* The maximum value for this is the value returned by IDirect3D::GetAdapte=
rCount().
+*
+* @param D3DDEVTYPE DeviceType
+* One of the D3DDEVTYPE enum members.
+*
+* @param D3DFORMAT AdapterFormat
+* One of the D3DFORMAT enum members except D3DFMT_UNKNOWN that the display=
 adapter mode where the test should occurr.
+*
+* @param D3DFORMAT RenderTargetFormat
+* One of the D3DFORMAT enum members except D3DFMT_UNKNOWN for the display =
adapter mode's render target format to be tested.
+*
+* @param D3DFORMAT DepthStencilFormat
+* One of the D3DFORMAT enum members except D3DFMT_UNKNOWN for the display =
adapter mode's depth-stencil format to be tested.
+*
+* @return HRESULT
+* If the DepthStencilFormat can be used with the RenderTargetFormat under =
the specified AdapterFormat,
+* the method returns D3D_OK.
+* If the DepthStencilFormat can NOT used with the RenderTargetFormat under=
 the specified AdapterFormat,
+* the method returns D3DERR_NOTAVAILABLE.
+* If Adapter is out of range, DeviceType is invalid,
+* AdapterFormat, RenderTargetFormat or DepthStencilFormat is invalid, the =
method returns D3DERR_INVALIDCALL.
