NAME
    CloseScreen -- Close an Intuition screen.

SYNOPSIS
    [Success =] CloseScreen( screen )
    [D0]                     A0

    [BOOL] CloseScreen( struct screen * );
    /* returns BOOL in V36 and greater */

FUNCTION
    Unlinks the screen, unlinks the viewport, deallocates everything that
    Intuition allocated when the screen was opened (using openscreen()).
    Doesn't care whether or not there are still any windows attached to the
    screen.  Doesn't try to close any attached windows; in fact, ignores
    them altogether (but see below for changes in V36).

    If this is the last screen to go, attempts to reopen Workbench.

    New for V36: this function will refuse to close the screen
    if there are windows open on the screen when CloseScreen() is
    called.  This avoids the almost certain crash when a screen
    is closed out from under a window.

INPUTS
    screen = pointer to the screen to be closed.

RESULT
    New for V36: returns TRUE (1) if screen is closed,
    returns FALSE (0) if screen had open windows when
    called.
