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

DXGKDDI_MONITORDESCRIPTORSET_ACQUIRENEXTDESCRIPTORINFO callback function

Description

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

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.
