DiveSetupBlitter Parameter - pSetupBlitter

pSetupBlitter (PSETUP_BLITTER) - input

Pointer to SETUP_BLITTER. This data structure contains parameters that will be used during the subsequent DiveBlitImage call. If this pointer is zero on input, this function will deinitialize the blitter and subsequent calls to DiveBlitImage will return DIVE_ERR_BLITTER_NOT_SETUP.

The ulStructLen field specifies the number of fields that are valid on input. Fields that are not specified as valid on input are considered to be unchanged from previous calls to DiveSetupBlitter. For example, if the visible rectangles have not changed, the structure length can be set to exclude the ulNumDstRects and pVisDstRects fields of SETUP_BLITTER, thereby enabling a performance optimization in the function.
