NAME
MrgCop -- Merge together coprocessor instructions.
SYNOPSIS
MrgCop( View )
A1
void MrgCop( struct View * );FUNCTION
Merge together the display, color, sprite and user coprocessor instructions into a single coprocessor instruction stream. This essentially creates a per-display-frame program for the coprocessor. This function MrgCop is used, for example, by the graphics animation routines which effectively add information into an essentially static background display. This changes some of the user or sprite instructions, but not those which have formed the basic display in the first place. When all forms of coprocessor instructions are merged together, you will have a complete per- frame instruction list for the coprocessor.
Restrictions: Each of the coprocessor instruction lists MUST be internally sorted in min to max Y-X order. The merge routines depend on this! Each list must be terminated using CEND(copperlist).
INPUTS
View - a pointer to the view structure whose coprocessor instructions are to be merged.
RESULT The view structure will now contain a complete, sorted/merged list of instructions for the coprocessor, ready to be used by the display processor. The display processor is told to use this new instruction stream through the instruction LoadView.
