IddCxSwapChainReleaseAndAcquireBuffer function (iddcx.h)

  • Article

An indirect display driver calls IddCxSwapChainReleaseAndAcquireBuffer to release the current buffer in the swap chain and acquire a new one. IDDs that report FP16 support must call IddCxSwapChainReleaseAndAcquireBuffer2 instead.

Syntax

HRESULT IddCxSwapChainReleaseAndAcquireBuffer(
  IDDCX_SWAPCHAIN                   SwapChainObject,
  IDARG_OUT_RELEASEANDACQUIREBUFFER *pOutArgs
);

Parameters

SwapChainObject

[in] The swap-chain object previously passed by the OS to the driver in a EVT_IDD_CX_MONITOR_ASSIGN_SWAPCHAIN call.

pOutArgs

[out] Pointer to an IDARG_OUT_RELEASEANDACQUIREBUFFER structure in which the output arguments of the function are returned.

Return value

IddCxSwapChainReleaseAndAcquireBuffer returns S_OK on success; otherwise it returns an appropriate error code.
