- Description
The TDx_DrawSurface::IsLost method will determine whether a surface's associated memory has been lost.
Possible ways memory could be lost may be the changing of display card mode or another application getting exclusive access to the display card and freeing all of the previously allocated surface memory.
If the method call fails, the OnError event will be triggered with one of the following values:
DDERR_INVALIDOBJECT
DDERR_INVALIDPARAMS
DDERR_SURFACELOST
