The pfnReleaseFrequencyRangeInfo function releases a D3DKMDT_MONITOR_FREQUENCY_RANGE structure that the VidPN manager previously provided to the display miniport driver.

Syntax

DXGKDDI_MONITORFREQUENCYRANGESET_RELEASEFREQUENCYRANGEINFO DxgkddiMonitorfrequencyrangesetReleasefrequencyrangeinfo;

NTSTATUS DxgkddiMonitorfrequencyrangesetReleasefrequencyrangeinfo(
  [in] IN_CONST_D3DKMDT_HMONITORFREQUENCYRANGESET hMonitorFrequencyRangeSet,
  [in] IN_CONST_PD3DKMDT_MONITOR_FREQUENCY_RANGE_CONST pMonitorFrequencyRangeInfo
)
{...}

A pointer to the D3DKMDT_MONITOR_FREQUENCY_RANGE structure that is to be released.
