-description

PFN_IDDCXSWAPCHAINRELEASEANDACQUIRESYSTEMBUFFER is a pointer to an OS callback function through which to release and acquire buffers from a swapchain.

-parameters

-param DriverGlobals [in]

Pointer to an IDD_DRIVER_GLOBALS structure containing system-defined per-driver data.

-param SwapChainObject [in]

The IDDCX_SWAPCHAIN object passed to the EVT_IDD_CX_MONITOR_ASSIGN_SWAPCHAIN call.

-param pOutArgs [out]

Output arguments of the functions.

-returns

PFN_IDDCXSWAPCHAINRELEASEANDACQUIRESYSTEMBUFFER returns S_OK; otherwise it returns an appropriate error code.

-remarks

An indirect display driver (IDD) should not use this pointer to directly call the function that it points to. IDDs should instead call IddCxSwapChainReleaseAndAcquireSystemBuffer.
