63        The function <STRONG>post_menu</STRONG> displays a menu to its associated subwindow.  To
64        trigger  physical  display  of  the  subwindow, use <STRONG><A HREF="curs_refresh.3x.html">refresh(3x)</A></STRONG> or some
65        equivalent <STRONG>curses</STRONG> routine (the implicit <STRONG>doupdate</STRONG> triggered by an <STRONG>curses</STRONG>
66        input  request  will do).  <STRONG>post_menu</STRONG> resets the selection status of all
67        items.
68
69        The function <STRONG>unpost_menu</STRONG> erases menu from its associated subwindow.

75        <STRONG>E_OK</STRONG> The routine succeeded.
76
77        <STRONG>E_SYSTEM_ERROR</STRONG>
78             System error occurred (see <STRONG>errno(3)</STRONG>).
79
80        <STRONG>E_BAD_ARGUMENT</STRONG>
81             Routine detected an incorrect or out-of-range argument.
82
83        <STRONG>E_POSTED</STRONG>
84             The menu has already been posted.
85
86        <STRONG>E_BAD_STATE</STRONG>
87             Routine was called from an initialization or termination function.
88
89        <STRONG>E_NO_ROOM</STRONG>
90             Menu is too large for  its  window.   You  should  consider  using
91             <STRONG>set_menu_format</STRONG> to solve the problem.
92
93        <STRONG>E_NOT_POSTED</STRONG>
94             The menu has not been posted.
95
96        <STRONG>E_NOT_CONNECTED</STRONG>
97             No items are connected to the menu.
