D3DDDIARG_PRESENT structure (d3dumddi.h)

The D3DDDIARG_PRESENT structure describes a resource to display.

Syntax

typedef struct _D3DDDIARG_PRESENT {
  [in] HANDLE                   hSrcResource;
  [in] UINT                     SrcSubResourceIndex;
  [in] HANDLE                   hDstResource;
       UINT                     DstSubResourceIndex;
  [in] D3DDDI_PRESENTFLAGS      Flags;
  [in] D3DDDI_FLIPINTERVAL_TYPE FlipInterval;
} D3DDDIARG_PRESENT;

Members

[in] hSrcResource

A handle to the source resource to display. hSrcResource can be NULL if the user-mode display driver should perform a color-fill operation to the screen.

[in] SrcSubResourceIndex

The zero-based index into the source resource, which is specified by the handle in the hSrcResource member. This index indicates the subresource or surface to display.

[in] hDstResource

A handle to the destination resource to display to. If NULL, the user-mode display driver is informed that a color-fill operation will occur, but the user-mode driver is not expected to perform the operation. The display miniport driver does the actual color-fill operation and will be informed of the color value at that time.

DstSubResourceIndex

[in] The zero-based index into the destination resource, which is specified by the handle in the hDstResource member. This index indicates the subresource or surface to display to.

[in] Flags

A D3DDDI_PRESENTFLAGS structure that identifies, in bit-field flags, how to display.

[in] FlipInterval

A D3DDDI_FLIPINTERVAL_TYPE-typed value that indicates the flip interval (that is, if the flip occurs after zero, one, two, three, or four vertical syncs).
