NAME

       dtk_create_window, dtk_close - Create and destroy a window

SYNOPSIS

       #include <drawtk.h>

       dtk_hwnd dtk_create_window(unsigned int width, unsigned int height,
                     unsigned int x, unsigned int y,
                     unsigned int bpp, const char *caption);
       void dtk_close(const dtk_hwnd wnd);

DESCRIPTION

       dtk_create_window()  creates  a  window  of  size  (width,height)  to be used later as the target of next
       drawings. If width or height is zero, then the created window will be full screen. Arguments x and y have
       currently no effect. bpp specifies the number of "bits  per  pixel"  the  underlying  OpenGL  framebuffer
       should support. caption specifies the name of the window that the window manager should display.

       The  inner  frame  size  for drawings depends on the aspect ratio of the window.  The origin (0,0) of the
       frame is always the the center of the window. The smallest dimension of the window is equal to 2  in  the
       drawing coordinates, so that a draw made in the box between (-1,-1) and (1,1) always fits in the window.

       dtk_close() destroys an unused window.

RETURN VALUE

       dtk_create_window() returns an handle to the created window. On error, this function returns NULL.

       dtk_close() returns no value.

LIMITATIONS

       For the moment only one window can be created. Any subsequent call to dtk_create_window() will fail. This
       is due to the underlying SDL version used which supports only one window.
