DXGKCB_QUERYMONITORINTERFACE callback function (d3dkmddi.h)
DXGKCB_QUERYMONITORINTERFACE obtains a pointer to a DXGK_MONITOR_INTERFACE structure, which contains pointers to functions that the display miniport driver can call to obtain other interfaces that provide access to monitor descriptors, modes, and frequency ranges.
Syntax
DXGKCB_QUERYMONITORINTERFACE DxgkcbQuerymonitorinterface;
NTSTATUS DxgkcbQuerymonitorinterface(
[in] IN_CONST_HANDLE hAdapter,
[in] IN_CONST_DXGK_MONITOR_INTERFACE_VERSION MonitorInterfaceVersion,
[out] DEREF_OUT_CONST_PPDXGK_MONITOR_INTERFACE ppMonitorInterface
)
{...}
Parameters
[in] hAdapter
A handle that represents a display adapter. The VidPN manager provided this handle to the display miniport driver in a call to DxgkDdiRecommendFunctionalVidPn, DxgkDdiIsSupportedVidPn, DxgkDdiEnumVidPnCofuncModality, or DxgkDdiCommitVidPn.
[in] MonitorInterfaceVersion
A value from the DXGK_MONITOR_INTERFACE_VERSION enumeration that specifies the version of the monitor interface being requested.
[out] ppMonitorInterface
A pointer to a pointer to the DXGK_MONITOR_INTERFACE structure.
Return value
DXGKCB_QUERYMONITORINTERFACE returns STATUS_SUCCESS if it succeeds. Otherwise, it returns one of the error codes defined in Ntstatus.h.
Remarks
DXGKCB_XXX functions are implemented by Dxgkrnl. To use this callback function, call DxgkCbQueryMonitorInterface via the DXGKRNL_INTERFACE.
