NAME
    NextPubScreen -- Identify next public screen in the cycle. (V36)

SYNOPSIS
    Buff = NextPubScreen( screen, namebuff )
    D0                    A0      A1

    UBYTE *NextPubScreen( struct screen *, ubyte * );

FUNCTION
    Returns name of next public screen in system rotation, to
    allow visitor windows to provide function to "jump" among
    public-screens in a cycle.

INPUTS
    screen = pointer to the screen your window is currently open in,
      or NULL, if you don't have a pointer to a public screen.
    NameBuff = pointer to a buffer of MAXPUBSCREENNAME+1 characters,
      for Intuition to fill in with the name of the next public
      screen in rotation.

RESULT
    Returns NULL if there are no public screens, otherwise a
    pointer to your NameBuff.

NOTES
    There is no guarantee that the public screen whose name
    was returned by this function will exist or be in "public" state
    by the time you call lockpubscreen(), etc.  you must handle
    cases where lockpubscreen(), etc. will fail.

BUGS
    Due to a bug, your buffer needs to be (MAXPUBSCREENNAME + 1)
    characters big, which is one more than originally documented.

    The starting screen and cycle order of the public screens isn't
    defined, so do not draw conclusions about the order you
    see in the current version of Intuition.  We reserve the
    right to add meaning to the ordering at a future time.
