Syntax

HRESULT Present(
  [in, size_is(cxFrameBuffer * cyFrameBuffer * (cBitsPerPixel / 8)] const BYTE *pbFrameBuffer,
  [in]                                                                    UINT cxFrameBuffer,
  [in]                                                                    UINT cyFrameBuffer,
  [in]                                                                    UINT cBitsPerPixel,
  [in]                                                              const HRGN hRgnDirty
);

Parameters

pbFrameBuffer [in]

A pointer to the frame buffer to display.

cxFrameBuffer [in]

The width of the frame buffer, in pixels.

cyFrameBuffer [in]

The height of the frame buffer, in pixels.

cBitsPerPixel [in]

The color depth of the bitmap, in bits per pixel.

hRgnDirty [in]

A handle to the dirty region of the frame buffer. This is the portion of the frame buffer that is to be updated.

Return value

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
