66        Every  menu  has an associated pair of <STRONG>curses</STRONG> windows.  The menu window
67        displays any title and border associated  with  the  window;  the  menu
68        subwindow  displays  the items of the menu that are currently available
69        for selection.
70
71        The first four  functions  get  and  set  those  windows.   It  is  not
72        necessary to set either window; by default, the driver code uses <STRONG>stdscr</STRONG>
73        for both.
74
75        In the <STRONG>set_</STRONG> functions, window argument of <STRONG>NULL</STRONG> is treated as though  it
76        were <STRONG>stsdcr</STRONG>.  A menu argument of <STRONG>NULL</STRONG> is treated as a request to change
77        the system default menu window or subwindow.
78
79        The function <STRONG>scale_menu</STRONG> returns  the  minimum  size  required  for  the
80        subwindow of <EM>menu</EM>.
81

83 </PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
84        Routines  that  return  pointers  return  <STRONG>NULL</STRONG> on error.  Routines that
85        return an integer return one of the following error codes:
86
87        <STRONG>E_OK</STRONG> The routine succeeded.
88
89        <STRONG>E_SYSTEM_ERROR</STRONG>
90             System error occurred (see <STRONG>errno(3)</STRONG>).
91
92        <STRONG>E_BAD_ARGUMENT</STRONG>
93             Routine detected an incorrect or out-of-range argument.
94
95        <STRONG>E_POSTED</STRONG>
96             The menu has already been posted.
97
98        <STRONG>E_NOT_CONNECTED</STRONG>
99             No items are connected to the menu.
