SDL_CreateWindow() and multiple displays

Hi,

When I call SDL_CreateWindow() it seems to just "figure out" which display
to make the window appear on. Can someone tell me how SDL makes
this happen?

As far as windows are concerned if I'm not mistaken SDL considers that all displays are in a space, that space being defined at [0 , 0] by the upper left corner pixel of the primary display. If you change the position of your window you can take it to other screens using SDL_GetDisplayBounds() for reference.
