DXGKARG_VALIDATEUPDATEALLOCPROPERTY structure

Description

The DXGKARG_VALIDATEUPDATEALLOCPROPERTY structure holds the information needed to validate the parameters to update the properties of an allocation.

Members

hAllocation [in]

A handle to the allocation that will be updated.

SupportedSegmentSet [in]

An index for the new supported segment set. If the current supported segment set is the same, then this will be ignored.

PreferredSegment [in]

An index for the new preferred segment set. If the current preferred segment set is the same, then this will be ignored.

Flags [in]

A D3DDDI_UPDATEALLOCPROPERTY_FLAGS structure with flags that specify how to update the allocation's properties.

SetAccessedPhysically

A UINT value that specifies whether the allocation is accessed by its physical address.

SetSupportedSegmentSet

A UINT value that specifies whether the supported segment is set to a new value.

SetPreferredSegment

A UINT value that specifies whether the preferred segment is set to a new value.

Reserved

This member is reserved and should be set to zero.

PropertyMaskValue

An alternative way to access the property mask values.
