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

These routines return one of the following:
|
|
|
|
<STRONG>E_OK</STRONG> The routine succeeded.
|
|
|
|
<STRONG>E_SYSTEM_ERROR</STRONG>
|
|
System error occurred (see <STRONG>errno(3)</STRONG>).
|
|
|
|
<STRONG>E_BAD_ARGUMENT</STRONG>
|
|
Routine detected an incorrect or out-of-range argument.
|
|
|
|
<STRONG>E_POSTED</STRONG>
|
|
The menu has already been posted.
|
|
|
|
<STRONG>E_BAD_STATE</STRONG>
|
|
Routine was called from an initialization or termination function.
|
|
|
|
<STRONG>E_NO_ROOM</STRONG>
|
|
Menu is too large for its window. You should consider using
|
|
<STRONG>set_menu_format</STRONG> to solve the problem.
|
|
|
|
<STRONG>E_NOT_POSTED</STRONG>
|
|
The menu has not been posted.
|
|
|
|
<STRONG>E_NOT_CONNECTED</STRONG>
|

No items are connected to the menu.
