NAME
menu_spacing − Control spacing between menu items.
SYNOPSIS
#include
<menu.h>
int set_menu_spacing(MENU *menu,
int spc_description,
int spc_rows,
int spc_columns);
int menu_spacing(const MENU *menu,
int* spc_description,
int* spc_rows,
int* spc_columns);
DESCRIPTION
The function
set_menu_spacing sets the spacing information for the
menu. Its parameter spc_description controls the
number of spaces between an item name and an item
description. It must not be larger than TABSIZE. The
menu system puts in the middle of this spacing area the pad
character. The remaining parts are filled with spaces. The
spc_rows parameter controls the number of rows that
are used for an item. It must not be larger than 3. The menu
system inserts the blank lines between item rows, these
lines will contain the pad character in the appropriate
positions. The spc_columns parameter controls the
number of blanks between columns of items. It must not be
larger than TABSIZE. A value of 0 for all the spacing values
resets them to the default, which is 1 for all of them.
The function menu_spacing passes back the spacing
info for the menu. If a pointer is NULL, this specific info
is simply not returned.
RETURN VALUE
Both routines return E_OK on success. set_menu_spacing may return E_POSTED if the menu is posted, or E_BAD_ARGUMENT if one of the spacing values is out of range.

NOTES
The header file <menu.h> automatically includes the header file <curses.h>.
PORTABILITY
These routines are specific to ncurses. They were not supported on Version 7, BSD or System V implementations. It is recommended that any code depending on them be conditioned using NCURSES_VERSION.
