D3DHAL_DP2SETPRIORITY structure (d3dhal.h)

  • Article

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

Syntax

typedef struct _D3DHAL_DP2SETPRIORITY {
  DWORD dwDDSurface;
  DWORD dwPriority;
} D3DHAL_DP2SETPRIORITY;

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.
