IDXGISwapChain1::GetHwnd method

Retrieves the underlying HWND for this swap-chain object.

Syntax

HRESULT GetHwnd(
  [out] HWND *pHwnd
);

Parameters

pHwnd [out]

A pointer to a variable that receives the HWND for the swap-chain object.

Return value

Returns S_OK if successful; an error code otherwise. For a list of error codes, see DXGI_ERROR.

If pHwnd receives NULL (that is, the swap chain is not HWND-based), GetHwnd returns DXGI_ERROR_INVALID_CALL.

Remarks

Applications call the IDXGIFactory2::CreateSwapChainForHwnd method to create a swap chain that is associated with an HWND.
