Flush(D3D10) routine

The Flush(D3D10) function submits outstanding hardware commands that are in the hardware command buffer to the display miniport driver.

Syntax


PFND3D10DDI_FLUSH Flush;

VOID APIENTRY Flush(
  _In_  D3D10DDI_HDEVICE hDevice
)
{ ... }

Parameters

hDevice [in]

A handle to the display device (graphics context).

Return value

None

The driver can use the pfnSetErrorCb callback function to set an error code. For more information about setting error codes, see the following Remarks section.

Remarks

After the Flush(D3D10) function completes, all previously issued commands no longer depend on actions that occur within the application's user-mode context. In addition, applications can safely suspend themselves without blocking rendering until the kernel restarts them (such as, when an asynchronous query is used).

The driver should not encounter any error, except for D3DDDIERR_DEVICEREMOVED. Therefore, if the driver passes any error, except for D3DDDIERR_DEVICEREMOVED, in a call to the pfnSetErrorCb function, the Direct3D runtime will determine that the error is critical. Even if the device was removed, the driver is not required to return D3DDDIERR_DEVICEREMOVED; however, if device removal interfered with the operation of Flush(D3D10) (which typically should not happen), the driver can return D3DDDIERR_DEVICEREMOVED.

Requirements

Version

Available in Windows Vista and later versions of the Windows operating systems.
