Red Bear OS is a full fork. All sources must be available from git clone with zero network access. Removed gitignore rules that excluded fetched source trees under recipes/*/source/, local/recipes/kde/*/source/, local/recipes/qt/*/source/, and vendor source trees. Build artifacts (target/, build/, source.tar, *.o, *.so) remain excluded. 127291 files added — kernel, relibc, base, bootloader, pkgar, all KDE/Qt frameworks, mesa, wayland, DRM drivers, and every other recipe source.

.SH NAME

\fBmitem_current\fP \-
|
|
set and get current_menu_item
|
|
.SH SYNOPSIS
|
|
.nf
|
|
\fB#include <menu.h>
|
|
.PP
|
|
\fBint set_current_item(MENU *\fImenu\fP, ITEM *\fIitem\fP);
|
|
\fBITEM *current_item(const MENU *\fImenu\fP);
|
|
.PP
|
|
\fBint set_top_row(MENU *\fImenu\fP, int \fIrow\fP);
|

|
|
.PP
|
|
\fBint item_index(const ITEM *\fIitem\fP);
|
|
.fi
|
|
.SH DESCRIPTION
|
|
The function \fBset_current_item\fP sets the current item (the item on which
|
|
the menu cursor is positioned).
|
|
\fBcurrent_item\fP returns a pointer to the
|
|
current item in the given menu.
|
|
.PP
|
|
The function \fBset_top_row\fP sets the top row of the menu to show the given
|
|
row (the top row is initially 0, and is reset to this value whenever the
|
|
\fBO_ROWMAJOR\fP option is toggled).
|
|
The item leftmost on the given row
|
|
becomes current.
|
|
The function \fBtop_row\fP returns the number of the top menu
|
|
row being displayed.
|
|
.PP
|
|
The function \fBitem_index\fP returns the (zero-origin) index of \fIitem\fP in
|
|
the menu's item pointer list.
|
|
.SH RETURN VALUE
|
|
\fBcurrent_item\fP returns a pointer (which may be
|
|
.IR NULL ")."
|
|
It does not set \fBerrno\fP.
|
|
.PP
|
|
\fBtop_row\fP and \fBitem_index\fP return \fBERR\fP (the general \fBcurses\fP
|
|
error value) if their \fImenu\fP parameter is
|
|
.IR NULL "."
|
|
.PP
|
|
\fBset_current_item\fP and \fBset_top_row\fP return one of the following:
|
|
.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_NOT_CONNECTED
|
|
No items are connected to the menu.
|
|
.TP 5
|
|
.B E_SYSTEM_ERROR
|
|
System error occurred (see \fBerrno\fP(3)).
|
|
.SH PORTABILITY
|
|
These routines emulate the System V menu library.
|
|
They were not supported on
|
|
Version 7 or BSD versions.
|
|
.PP
|
|
The SVr4 menu library documentation specifies the \fBtop_row\fP and
|
|
\fBindex_item\fP error value as \-1 (which is the value of \fBERR\fP).
