DXGKDDI_MONITORFREQUENCYRANGESET_ACQUIRENEXTFREQUENCYRANGEINFO callback function

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

Syntax

DXGKDDI_MONITORFREQUENCYRANGESET_ACQUIRENEXTFREQUENCYRANGEINFO DxgkddiMonitorfrequencyrangesetAcquirenextfrequencyrangeinfo;

NTSTATUS DxgkddiMonitorfrequencyrangesetAcquirenextfrequencyrangeinfo(
  IN_CONST_D3DKMDT_HMONITORFREQUENCYRANGESET hMonitorFrequencyRangeSet,
  IN_CONST_PD3DKMDT_MONITOR_FREQUENCY_RANGE_CONST pMonitorFrequencyRangeInfo,
  DEREF_OUT_CONST_PPD3DKMDT_MONITOR_FREQUENCY_RANGE ppNextMonitorFrequencyRangeInfo
)
{...}

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.
