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.
