Windows Driver Kit DDI reference (nc-d3dkmddi-dxgkddi_monitorfrequencyrangeset_acquirenextfrequencyrangeinfo)

DXGKDDI_MONITORFREQUENCYRANGESET_ACQUIRENEXTFREQUENCYRANGEINFO callback function

Description

The pfnAcquireNextFrequencyRangeInfo function returns the next frequency range descriptor in a monitor frequency range set, given the current frequency range descriptor.

Parameters

`hMonitorFrequencyRangeSet` [in]

A handle to a monitor frequency range set object. The display miniport driver previously obtained this handle by calling the pfnGetMonitorFrequencyRangeSet function of the Monitor Interface.

`pMonitorFrequencyRangeInfo` [in]

A pointer to a D3DKMDT_MONITOR_FREQUENCY_RANGE structure that is the current frequency range descriptor. The display miniport driver previously obtained this pointer by calling pfnAcquireFirstFrequencyRangeInfo or pfnAcquireNextFrequencyRangeInfo.

`ppNextMonitorFrequencyRangeInfo` [out]

A pointer to a variable that receives a pointer to a D3DKMDT_MONITOR_FREQUENCY_RANGE structure that is the next frequency range descriptor.

Return value

The pfnAcquireNextFrequencyRangeInfo function returns one of the following values.

Return code	Description
STATUS_SUCCESS	The function successfully returned the next frequency range descriptor.
STATUS_GRAPHICS_DATASET_IS_EMPTY	The function succeeded, but there were no more frequency range descriptors in the set.
STATUS_INVALID_PARAMETER	An invalid parameter was supplied.
STATUS_INVALID_FREQUENCYRANGE	The frequency range descriptor supplied in pMonitorFrequencyRangeInfo was invalid.
STATUS_INVALID_MONITOR_FREQUENCYRANGESET	The handle supplied in hMonitorFrequencyRangeSet was invalid.

This function might also return other error codes defined in Ntstatus.h.

Remarks

When you have finished using the D3DKMDT_MONITOR_FREQUENCY_RANGE structure, you must release the structure by calling pfnReleaseFrequencyRangeInfo.

You can obtain all the descriptors in a monitor frequency range set by calling pfnAcquireFirstFrequencyRangeInfo and then making a sequence of calls to pfnAcquireNextFrequencyRangeInfo.
