| .SH NAME |
| \fBmenu\fR \- curses extension for programming menus |
| .SH SYNOPSIS |
| \fB#include <menu.h>\fR |
| .br |
| .SH DESCRIPTION |
| The \fBmenu\fR library provides terminal-independent facilities for composing |
| menu systems on character-cell terminals. The library includes: item routines, |
| which create and modify menu items; and menu routines, which group items into |
| menus, display menus on the screen, and handle interaction with the user. |
| .PP |
| The \fBmenu\fR library uses the \fBcurses\fR libraries, and a curses |
| initialization routine such as \fBinitscr\fR must be called before using any of |
| these functions. To use the \fBmenu\fR library, link with the options |
| \fB\-lmenu \-lcurses\fR. |
| . |
| .SS Current Default Values for Item Attributes |
| . |
| The \fBmenu\fR library maintains a default value for item attributes. You can |
| get or set this default by calling the appropriate \fBget_\fR or \fBset_\fR |
| routine with a \fBNULL\fR item pointer. Changing this default with a |
| \fBset_\fR function affects future item creations, but does not change the |
| rendering of items already created. |
| . |
| .SS Routine Name Index |
| . |
| The following table lists each \fBmenu\fR routine and the name of |
| the manual page on which it is described. |

| .SH RETURN VALUE |
| Routines that return pointers return \fBNULL\fR on error. Routines that return |
| an integer return one of the following error codes: |
| .TP 5 |
| .B E_OK |
| The routine succeeded. |
| .TP 5 |
| .B E_BAD_ARGUMENT |
| Routine detected an incorrect or out-of-range argument. |
| .TP 5 |
| .B E_BAD_STATE |
| Routine was called from an initialization or termination function. |
| .TP 5 |
| .B E_NO_MATCH |
| Character failed to match. |
| .TP 5 |
| .B E_NO_ROOM |
| Menu is too large for its window. |
| .TP 5 |
| .B E_NOT_CONNECTED |
| No items are connected to the menu. |
| .TP 5 |
| .B E_NOT_POSTED |
| The menu has not been posted. |
| .TP 5 |
| .B E_NOT_SELECTABLE |
| The designated item cannot be selected. |
| .TP 5 |
| .B E_POSTED |
| The menu is already posted. |
| .TP 5 |
| .B E_REQUEST_DENIED |
| The menu driver could not process the request. |
| .TP 5 |
| .B E_SYSTEM_ERROR |
| System error occurred (see \fBerrno\fR). |
| .TP 5 |
| .B E_UNKNOWN_COMMAND |
| The menu driver code saw an unknown request code. |
| .SH NOTES |
| The header file \fB<menu.h>\fR automatically includes the header files |
| \fB<curses.h>\fR and \fB<eti.h>\fR. |
| .PP |
| In your library list, libmenu.a should be before libncurses.a; that is, |
| you want to say `\-lmenu \-lncurses', not the other way around (which would |
| usually give a link-error). |
| .SH PORTABILITY |
| These routines emulate the System V menu library. They were not supported on |
| Version 7 or BSD versions. |
| .SH AUTHORS |
| Juergen Pfeifer. Manual pages and adaptation for ncurses by Eric |
| S. Raymond. |
| .SH SEE ALSO |
| \fBcurses\fR(3X) and related pages whose names begin "menu_" for detailed |
| descriptions of the entry points. |
