59 WINDOW *menu_win(const MENU *menu);

66 <H2>DESCRIPTION</H2><PRE>
67 Every menu has an associated pair of <STRONG>curses</STRONG> windows. The
68 menu window displays any title and border associated with
69 the window; the menu subwindow displays the items of the
70 menu that are currently available for selection.
72 The first four functions get and set those windows. It is
73 not necessary to set either window; by default, the driver
74 code uses <STRONG>stdscr</STRONG> for both.
76 In the <STRONG>set_</STRONG> functions, window argument of <STRONG>NULL</STRONG> is treated
77 as though it were <STRONG>stsdcr</STRONG>. A menu argument of <STRONG>NULL</STRONG> is
78 treated as a request to change the system default menu
81 The function <STRONG>scale_menu</STRONG> returns the minimum size required
82 for the subwindow of <EM>menu</EM>.
86 <H2>RETURN VALUE</H2><PRE>
87 Routines that return pointers return <STRONG>NULL</STRONG> on error. Rou-
88 tines that return an integer return one of the following
91 <STRONG>E_OK</STRONG> The routine succeeded.
93 <STRONG>E_SYSTEM_ERROR</STRONG>
94 System error occurred (see <STRONG>errno</STRONG>).
96 <STRONG>E_BAD_ARGUMENT</STRONG>
97 Routine detected an incorrect or out-of-range argu-
100 <STRONG>E_POSTED</STRONG>
101 The menu has already been posted.
103 <STRONG>E_NOT_CONNECTED</STRONG>
