NAME
set_menu_spacing, menu_spacing - set and get 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 be-
tween 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 num-
ber 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.
