I'm trying to figure out how to program the mouse but I've got a
problem. The function below never changes the value of 'pressed', and
I'm not sure why.. The row and cursor are returned ok.

void get_mouse_status(int *pressed, int *column, int *row)
{
 asm ("
     movw $0x0003,%%ax \n
     int  $0x33        \n
     movw %%bx,%0      \n
     movw %%cx,%1      \n
     movw %%dx,%2"
     :
     : "g" (*pressed), "g" (*column), "g" (*row)
     : "ax", "bx", "cx", "dx", "memory"
 );
}
