DD_STEREOMODE structure (ddrawint.h)

  • Article

The DD_STEREOMODE structure is used by the runtime with GUID_DDStereoMode in a DdGetDriverInfo call to query whether the driver supports stereo for a given video display mode.

Syntax

typedef struct _DD_STEREOMODE {
  DWORD dwSize;
  DWORD dwHeight;
  DWORD dwWidth;
  DWORD dwBpp;
  DWORD dwRefreshRate;
  BOOL  bSupported;
} *PDD_STEREOMODE, DD_STEREOMODE;

Members

dwSize

Specifies the size in bytes of the DD_STEREOMODE structure.

dwHeight

Specifies the height in scan lines of the display mode. Has the value D3DGDI2_MAGIC if this structure is, in fact, a DD_GETDRIVERINFO2DATA call.

dwWidth

Specifies the width in pixels of the display mode.

dwBpp

Specifies the bits per pixel of the display mode.

dwRefreshRate

Specifies the refresh rate in hertz of the display mode.

bSupported

Driver sets to TRUE if stereo is supported with the specified display mode, or FALSE otherwise.

Remarks

To check each display mode to see if the driver supports stereo with that mode, the runtime calls the driver's DdGetDriverInfo function. In this call, the runtime specifies GUID_DDStereoMode in the guidInfo member of the DD_GETDRIVERINFODATA structure to which the lpGetDriverInfo parameter points. The runtime also provides a pointer to a DD_STEREOMODE structure in the lpvData member of DD_GETDRIVERINFODATA. The driver returns DD_OK if it supports GUID_DDStereoMode and sets the bSupported member of DD_STEREOMODE to TRUE if it supports stereo with the specified display mode.

GUID_DDStereoMode provides a way to turn OFF stereo per-mode, since it is expected that a driver that can do stereo can do stereo in any mode.
