_D3DHAL_DP2SETPRIORITY structure

Description

The D3DHAL_DP2SETPRIORITY structure is used to inform the driver of the priority of the texture specified by the handle dwDDDestSurface.

Members

dwDDSurface

Specifies the handle of the texture.

dwPriority

Specifies the priority of the dwDDDestSurface texture. A texture's priority value can be set anywhere in the range from 0 to 0xFFFFFFFF.

Remarks

Drivers are notified of handles at texture creation time. The driver can expect to receive priority notifications only for driver-managed textures.

Priorities determine when managed textures are to be evicted from memory. A texture assigned a low priority is evicted before a texture with a high priority. If two textures have the same priority, the texture that was used more recently is kept in memory; the other texture is evicted.
