  • Article

Describes info that's used to update a destination subresource region from a source system-memory region. Used by Windows Display Driver Model (WDDM) 1.3 and later user-mode display drivers.

Syntax

typedef struct D3DDDIARG_UPDATESUBRESOURCEUP {
  HANDLE              hResource;
  UINT                SubResourceIndex;
  D3DDDIBOX           DstBox;
  const VOID          *pSysMemUP;
  UINT                RowPitch;
  UINT                DepthPitch;
  D3DDDIARG_COPYFLAGS Flags;
} D3DDDIARG_UPDATESUBRESOURCEUP;
