IDirectDrawSurface7::GetPriority method (ddraw.h)

  • Article

Retrieves the texture-management priority for this texture. This method succeeds only on managed textures.

Syntax

HRESULT GetPriority(
  [out] LPDWORD unnamedParam1
);

Parameters

[out] unnamedParam1

A pointer to a variable that receives the texture priority if the call succeeds.

Return value

If the method succeeds, the return value is DD_OK.

If it fails, the return value is an error. The method returns DDERR_INVALIDOBJECT if the parameter is invalid or if the texture is not managed by Direct3D.

Remarks

Priorities are used to determine when managed textures are to be removed from memory. A texture assigned a low priority is removed 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 removed.

Applications can set and retrieve priorities only for managed textures (those surfaces that were created with the DDSCAPS2_TEXTUREMANAGE flag). If you call GetPriority on a nonmanaged texture, GetPriority fails and returns DDERR_INVALIDOBJECT.

GetPriority was introduced with the IDirectDrawSurface7 interface.
