| 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 | .PP
|
|---|
| 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

|
|---|
| 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 | .PP
|
|---|
| 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 | usually give a link-error).
|
|---|
| 179 | .SH PORTABILITY
|
|---|
| 180 | These routines emulate the System V menu library. They were not supported on
|
|---|
| 181 | Version 7 or BSD versions.
