Re: A92: how to draw lines and stuff with TI-GCC


You sould write an assembler interface like this:

#define clrscr graphlib__0005
#define fillrect graphlib__0000
#define pause userlib__0000

void fill(),fillrect(),clrscr(),pause();
int _ti89,_ti92plus;

_main()
{
      clrscr();
      fill(10,10,135,10,0);
      pause();
};

void fill(x,y,width,height,color)   /* interface inline assembler */
int x;
int y;
int width;
int height;
int color;
{
asm("
           move.w 8(%sp),%d0
           move.w 10(%sp),%d1
           move.w 12(%sp),%d2
           move.w 14(%sp),%d3
           move.w 16(%sp),%d4
       ");
fillrect();
};
