<STRONG>menu</STRONG> - curses extension for programming menus
</PRE><H2><a name="h2-SYNOPSIS">SYNOPSIS</a></H2><PRE>
<STRONG>#include</STRONG> <STRONG>&lt;menu.h&gt;</STRONG>
</PRE><H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE>
The <STRONG>menu</STRONG> library provides terminal-independent facilities
for composing menu systems on character-cell terminals.
The library includes: item routines, which create and mod-
ify menu items; and menu routines, which group items into
menus, display menus on the screen, and handle interaction
with the user.
The <STRONG>menu</STRONG> library uses the <STRONG>curses</STRONG> libraries, and a curses
initialization routine such as <STRONG>initscr</STRONG> must be called
before using any of these functions. To use the <STRONG>menu</STRONG>
library, link with the options <STRONG>-lmenu</STRONG> <STRONG>-lcurses</STRONG>.
</PRE><H3><a name="h3-Current-Default-Values-for-Item-Attributes">Current Default Values for Item Attributes</a></H3><PRE>
The <STRONG>menu</STRONG> library maintains a default value for item
attributes. You can get or set this default by calling
the appropriate <STRONG>get_</STRONG> or <STRONG>set_</STRONG> routine with a <STRONG>NULL</STRONG> item
pointer. Changing this default with a <STRONG>set_</STRONG> function
affects future item creations, but does not change the
rendering of items already created.

Routines that return pointers return <STRONG>NULL</STRONG> on error. Rou-
tines that return an integer return one of the following
error codes:
<STRONG>E_OK</STRONG> The routine succeeded.
<STRONG>E_BAD_ARGUMENT</STRONG>
Routine detected an incorrect or out-of-range argu-
ment.
<STRONG>E_BAD_STATE</STRONG>
Routine was called from an initialization or termina-
tion function.
<STRONG>E_NO_MATCH</STRONG>
Character failed to match.
<STRONG>E_NO_ROOM</STRONG>
Menu is too large for its window.
<STRONG>E_NOT_CONNECTED</STRONG>
No items are connected to the menu.
<STRONG>E_NOT_POSTED</STRONG>
The menu has not been posted.
<STRONG>E_NOT_SELECTABLE</STRONG>
The designated item cannot be selected.
<STRONG>E_POSTED</STRONG>
The menu is already posted.
<STRONG>E_REQUEST_DENIED</STRONG>
The menu driver could not process the request.
<STRONG>E_SYSTEM_ERROR</STRONG>
System error occurred (see <STRONG>errno</STRONG>).
<STRONG>E_UNKNOWN_COMMAND</STRONG>
The menu driver code saw an unknown request code.
</PRE><H2><a name="h2-NOTES">NOTES</a></H2><PRE>
The header file <STRONG>&lt;menu.h&gt;</STRONG> automatically includes the header
files <STRONG>&lt;curses.h&gt;</STRONG> and <STRONG>&lt;eti.h&gt;</STRONG>.
In your library list, libmenu.a should be before libn-
curses.a; that is, you want to say `-lmenu -lncurses', not
the other way around (which would usually give a link-
error).
</PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
These routines emulate the System V menu library. They
were not supported on Version 7 or BSD versions.
