DXGKDDI_MONITORDESCRIPTORSET_ACQUIRENEXTDESCRIPTORINFO callback function (d3dkmddi.h)

The pfnAcquireNextDescriptorInfo function returns the next descriptor in a monitor descriptor set, given the current descriptor.

Syntax

DXGKDDI_MONITORDESCRIPTORSET_ACQUIRENEXTDESCRIPTORINFO DxgkddiMonitordescriptorsetAcquirenextdescriptorinfo;

NTSTATUS DxgkddiMonitordescriptorsetAcquirenextdescriptorinfo(
  IN_CONST_D3DKMDT_HMONITORDESCRIPTORSET hMonitorDescriptorSet,
  IN_CONST_PD3DKMDT_MONITOR_DESCRIPTOR_CONST pMonitorDescriptorInfo,
  DEREF_OUT_CONST_PPD3DKMDT_MONITOR_DESCRIPTOR ppNextMonitorDescriptorInfo
)
{...}

Parameters

hMonitorDescriptorSet

[in] A handle to a monitor descriptor set object. The display miniport driver previously obtained this handle by calling the pfnGetMonitorDescriptorSet function of the Monitor interface.

pMonitorDescriptorInfo

[in] A pointer to a D3DKMDT_MONITOR_DESCRIPTOR structure that is the current descriptor. The display miniport driver previously obtained this pointer by calling pfnAcquireFirstDescriptorInfo or pfnAcquireNextDescriptorInfo.

ppNextMonitorDescriptorInfo

[out] A pointer to a variable that receives a pointer to a D3DKMDT_MONITOR_DESCRIPTOR structure. The structure is the next descriptor in the set.

Return value

The pfnAcquireNextDescriptorInfo function returns one of the following values.

Return code Description
STATUS_SUCCESS The function successfully returned the next descriptor in the set.
STATUS_GRAPHICS_NO_MORE_ELEMENTS_IN_DATASET The function succeeded, but there were no more descriptors in the set.
STATUS_INVALID_PARAMETER An invalid parameter was supplied.
STATUS_INVALID_MONITOR_DESCRIPTOR The descriptor supplied in pMonitorDescriptorInfo was invalid.
STATUS_GRAPHICS_INVALID_MONITOR_DESCRIPTORSET The handle supplied in hMonitorDescriptorSet was invalid.

Remarks

When you have finished using the D3DKMDT_MONITOR_DESCRIPTOR structure, you must release the structure by calling pfnReleaseDescriptorInfo.

You can obtain all the descriptors in a monitor descriptor set by calling pfnAcquireFirstDescriptorInfo and then making a sequence of calls to pfnAcquireNextDescriptorInfo.
