Description

PFN_IDDCXSWAPCHAININSYSTEMMEMORY is a pointer to an OS callback function through which to determine whether swapchain buffers are allocated in system memory.

Parameters

DriverGlobals [in]

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

SwapChainObject [in]

The IDDCX_SWAPCHAIN object passed to the EVT_IDD_CX_MONITOR_ASSIGN_SWAPCHAIN call.

pInSystemMemory [out]

Output arguments of the functions.

Return value

PFN_IDDCXSWAPCHAININSYSTEMMEMORY 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 IddCxSwapChainInSystemMemory.
