_DD_GETEXTENDEDMODECOUNTDATA structure

Description

DirectX 9.0 and later versions only.

DD_GETEXTENDEDMODECOUNTDATA is the data structure pointed to by the lpvData field of DD_GETDRIVERINFODATA for DD_GETDRIVERINFO2DATA queries with the type D3DGDI2_TYPE_GETEXTENDEDMODECOUNT.

Members

`gdi2`

Specifies a DD_GETDRIVERINFO2DATA structure that contains the GetDriverInfo2 data for the query.

`dwModeCount`

Receives the number of supported extended display modes.

`dwReserved`

Specifies a reserved field. Driver should not read or write.

Remarks

To handle D3DGDI2_TYPE_GETEXTENDEDMODECOUNT, the driver must store the number of extended display modes that it supports in the dwModeCount member of DD_GETEXTENDEDMODECOUNTDATA. Display modes are described by D3DDISPLAYMODE structures. For more information about D3DDISPLAYMODE, see the DirectX SDK documentation.
