I'm writing a game and I have a function that looks like this:

---------------------------------------------------------------------------------------

int *get_orders(void)
{
 int *neworders,
     x=mouse_x,
     y=mouse_y;

 if (mouse_b & 1)     //left button used to select
     {
     neworders[0]=x;
     neworders[1]=y;
     neworders[2]=SELECT;
     }
 else if (mouse_b & 2)  //right button used to move/attack
     {
     neworders[0]=mouse_x;
     neworders[1]=mouse_y;
     neworders[2]=MOVE;
     }
 else
     return NULL;
 return neworders;
}
---------------------------------------------------------------------------------------

now everything works well as long as I don't click the mouse.  If I do
the program crashes(SIGSEV type error).  If I comment out the
    neworders[0]=x;
    neworders[1]=y;
part it doesn't crash my program so I would assume that means it has
something to do with assigning the mouse_x and mouse_y values to
neworders(I'm not sure I did this right either though).  RHIDE tells me
there is a call frame traceback error in a nother function(when I use
the "run" option in rhide) and call allegro's scroll_screen function.
does anyone have any ideas on what I am doing wrong?  And what other
info do you need to know to figgure it out?
