## 4.3 glutSetWindow, glutGetWindow

`glutSetWindow` sets the current window; `glutGetWindow` returns the identifier of the current window.

Usage

    void glutSetWindow(int win);
    int glutGetWindow(void);

`win`
  Identifier of GLUT window to make the current window.

Description

`glutSetWindow` sets the current window; `glutGetWindow` returns the identifier of the current window. If no windows exist or the previously current window was destroyed, `glutGetWindow` returns zero. `glutSetWindow` does not change the layer in use for the window; this is done using `glutUseLayer`.
