The D3DKMTSetAllocationPriority function sets the priority level of a resource or list of allocations.

Syntax

NTSTATUS D3DKMTSetAllocationPriority(
  [in] const D3DKMT_SETALLOCATIONPRIORITY *unnamedParam1
);

Parameters

[in] unnamedParam1

A pointer to a D3DKMT_SETALLOCATIONPRIORITY structure that contains information for setting the priority level of a resource or list of allocations.

Return value

D3DKMTSetAllocationPriority returns one of the following values:

This function might also return other NTSTATUS values.

Remarks

The following code example demonstrates how an OpenGL ICD can use D3DKMTSetAllocationPriority to set the priority level of a resource (and therefore all of the allocations that are associated with the resource).

VOID SetResourcePriority(D3DKMT_HANDLE hDevice, D3DKMT_HANDLE hResource, UINT uiPriority)
{
    D3DKMT_SETALLOCATIONPRIORITY SetAllocationPriorityData;

    SetAllocationPriorityData.hDevice = hDevice;
    SetAllocationPriorityData.hResource = hResource;
    SetAllocationPriorityData.phAllocationList = NULL;
    SetAllocationPriorityData.AllocationCount = 0;
    SetAllocationPriorityData.Priorities = &uiPriority;

    (*pfnKTSetAllocationPriority)(&SetAllocationPriorityData);
}
