| 32 | .SH NAME | 
|---|
| 33 | \fBmenu\fR - curses extension for programming menus | 
|---|
| 34 | .SH SYNOPSIS | 
|---|
| 35 | \fB#include <menu.h>\fR | 
|---|
| 36 | .br | 
|---|
| 37 | .SH DESCRIPTION | 
|---|
| 38 | The \fBmenu\fR library provides terminal-independent facilities for composing | 
|---|
| 39 | menu systems on character-cell terminals.  The library includes: item routines, | 
|---|
| 40 | which create and modify menu items; and menu routines, which group items into | 
|---|
| 41 | menus, display menus on the screen, and handle interaction with the user. | 
|---|
| 42 |  | 
|---|
| 43 | The \fBmenu\fR library uses the \fBcurses\fR libraries, and a curses | 
|---|
| 44 | initialization routine such as \fBinitscr\fR must be called before using any of | 
|---|
| 45 | these functions.  To use the \fBmenu\fR library, link with the options | 
|---|
| 46 | \fB-lmenu -lcurses\fR. | 
|---|
| 47 |  | 
|---|
| 48 | .SS Current Default Values for Item Attributes | 
|---|
| 49 |  | 
|---|
| 50 | The \fBmenu\fR library maintains a default value for item attributes.  You can | 
|---|
| 51 | get or set this default by calling the appropriate \fBget_\fR or \fBset_\fR | 
|---|
| 52 | routine with a \fBNULL\fR item pointer.  Changing this default with a | 
|---|
| 53 | \fBset_\fR function affects future item creations, but does not change the | 
|---|
| 54 | rendering of items already created. | 
|---|
| 55 |  | 
|---|
| 56 | .SS Routine Name Index | 
|---|
| 57 |  |

| 58 | The following table lists each \fBmenu\fR routine and the name of |

| 169 | .SH SEE ALSO | 
|---|
| 170 | \fBcurses\fR(3X) and related pages whose names begin "menu_" for detailed | 
|---|
| 171 | descriptions of the entry points. | 
|---|
| 172 | .SH NOTES | 
|---|
| 173 | The header file \fB<menu.h>\fR automatically includes the header files | 
|---|
| 174 | \fB<curses.h>\fR and \fB<eti.h>\fR. | 
|---|
| 175 |  | 
|---|
| 176 | In your library list, libmenu.a should be before libncurses.a; that is, | 
|---|
| 177 | you want to say `-lmenu -lncurses', not the other way around (which would | 
|---|
| 178 | give you a link error using GNU \fBld\fR(1) and many other linkers). | 
|---|
| 179 | .SH PORTABILITY | 
|---|
| 180 | These routines emulate the System V menu library.  They were not supported on | 
|---|
| 181 | Version 7 or BSD versions. |
