<H2>NAME</H2><PRE>
<B>menu_post</B> - write or erase menus from associated subwin-
dows
</PRE>
<H2>SYNOPSIS</H2><PRE>
<B>#include</B> <B><menu.h></B>
int post_menu(MENU *menu);
int unpost_menu(MENU *menu);
</PRE>
<H2>DESCRIPTION</H2><PRE>
The function <B>post_menu</B> displays a menu to its associated
subwindow. To trigger physical display of the subwindow,
use <B>refresh</B> or some equivalent <B>curses</B> routine (the
implicit <B>doupdate</B> triggered by an <B>curses</B> input request
will do). <B>post_menu</B> resets the selection status of all
items.
The function <B>unpost_menu</B> erases menu from its associated
subwindow.
</PRE>
<H2>RETURN VALUE</H2><PRE>
These routines return one of the following:
<B>E_OK</B> The routine succeeded.
<B>E_SYSTEM_ERROR</B>
System error occurred (see <B>errno</B>).
<B>E_BAD_ARGUMENT</B>
Routine detected an incorrect or out-of-range argu-
ment.
<B>E_POSTED</B>
The menu has already been posted.
<B>E_BAD_STATE</B>
Routine was called from an initialization or termina-
tion function.
<B>E_NO_ROOM</B>
Menu is too large for its window. You should consider
to use <B>set_menu_format()</B> to solve the problem.
<B>E_NOT_POSTED</B>
The menu has not been posted.
<B>E_NOT_CONNECTED</B>
No items are connected to the menu.

</PRE>
<H2>NOTES</H2><PRE>
The header file <B><menu.h></B> automatically includes the header
file <B><curses.h></B>.
</PRE>
<H2>PORTABILITY</H2><PRE>
These routines emulate the System V menu library. They
were not supported on Version 7 or BSD versions.
