Strange parameter passing problems (KSH)
Hi all,
I'm having a rather peculiar problem involving parameter passing with declared functions in my shell script. Hope to get some advice here.
A brief description of my code is as follows:
Quote:
# assign target directory to variable rdir
rdir = /products
# method showmenu finds all subdirectories from a given directory, places their names in an array and then outputs them in the form of a menu
showmenu() {
set -A items $(find $1/* -type d -prune)
i=0
while ((i<${#items[i]}))
do
echo "$i. ${items[$i]}"
((i+=1))
done
}
# in the next part of program, call showmenu and pass variable rdir as the parameter
showmenu $rdir
However, I'm not getting the results I wanted. If I pass in $rdir, I'm going to end up referencing from the root (ie. / ) and printing out the root directory names (ie. bin, boot, dev, etc, home). However, if I hard code the directory location in place of $1 in showmenu(), I'll see the correct directory names.
Any ideas as to why the directory names are not showing?
Thanks in advance.

item_count
items(3MENU) items(3MENU)
NAME
menu_items - make and break connections between items and menus
SYNOPSIS
#include <menu.h>
int set_menu_items(MENU *menu, ITEM **items);
ITEM **menu_items(const MENU *menu);
int item_count(const MENU *menu);
DESCRIPTION
The function set_menu_items changes the item pointer array of the given menu. The array must be terminated by a NULL.
The function menu_items returns the item array of the given menu.
The function item_count returns the count of items in menu.
RETURN VALUES
The function menu_items returns a pointer (which may be NULL). It does not set errno.
The function item_count returns ERR (the general curses error return value) if its menu parameter is NULL.
The function set_menu_items returns one of the following codes on error:
E_OK The routine succeeded.
E_BAD_ARGUMENT
Routine detected an incorrect or out-of-range argument.
E_NOT_CONNECTED
No items are connected to the menu.
E_POSTED
The menu is already posted.
E_SYSTEM_ERROR
System error occurred (see errno).
SEE ALSO
ncurses(3NCURSES), menu(3MENU).
NOTES
The header file <menu.h> automatically includes the header file <curses.h>.
PORTABILITY
These routines emulate the System V menu library. They were not supported on Version 7 or BSD versions.
The SVr4 menu library documentation specifies the item_count error value as -1 (which is the value of ERR).
