I am having problems changing the shape of the mouse using interupts, my
code goes like follows,

I have a definition for mouses new shape like

static unsigned mousenewshape[]=
{
0x0001,
0xffff,
etc,
}


and I have a function defined as follows

Mouse_Shape(int hotx,int hoty,unsigned *mask)
{

   __dpmi_regs r;
   int c;

   for(c=0;c<=128;c++)
       _farpokeb(__dos_ds,(__tb & 0x000fffff)+c,mask[c]};

   r.x.dx = (__tb & 0x000fffff) & 0xffff;
   r.x.es = (__tb & 0x000fffff) & 0xffff0000 >>4;
   r.x.ax = 0x09;
   r.x.bx = hotx;
   r.x.cx = hoty;
   __dpmi_int(0x33,&r);

}

and I call it in the following way

Mouse_Shape(0,0,mousenewshape);


Yet this does not seem to work.

Has anyone any ideas?

Thanks in advance
