PFN_IDDCXSWAPCHAINRELEASEANDACQUIRESYSTEMBUFFER callback function (iddcx.h)
PFN_IDDCXSWAPCHAINRELEASEANDACQUIRESYSTEMBUFFER is a pointer to an OS callback function through which to release and acquire buffers from a swapchain.
Syntax
PFN_IDDCXSWAPCHAINRELEASEANDACQUIRESYSTEMBUFFER PfnIddcxswapchainreleaseandacquiresystembuffer;
HRESULT * PfnIddcxswapchainreleaseandacquiresystembuffer(
[in] PIDD_DRIVER_GLOBALS DriverGlobals,
[in] IDDCX_SWAPCHAIN SwapChainObject,
[out] IDARG_OUT_RELEASEANDACQUIRESYSTEMBUFFER *pOutArgs
)
{...}
Parameters
[in] DriverGlobals
Pointer to an IDD_DRIVER_GLOBALS structure containing system-defined per-driver data.
[in] SwapChainObject
The IDDCX_SWAPCHAIN object passed to the EVT_IDD_CX_MONITOR_ASSIGN_SWAPCHAIN call.
[out] pOutArgs
Output arguments of the functions.
Return value
PFN_IDDCXSWAPCHAINRELEASEANDACQUIRESYSTEMBUFFER returns S_OK; otherwise it returns an appropriate error code.
