I need to get two values from this function as below:
I need values of $pref and $avail from this function.Is there a way to combine these values and return as a 1 value since I understand that a function can return a single value .Thereafter after returning these values I can again get the 2 values in the code from where I called this function

For example:
sh script.sh yes no good bad
x=$#
while
do
echo (last argument, then second last etc until first argument)
let x=($x-1)
done
should print out
bad
good

prop_send_syscall
PROP_SEND_SYCALL(3) BSD Library Functions Manual PROP_SEND_SYCALL(3)NAME
prop_array_send_syscall, prop_array_recv_syscall, prop_dictionary_send_syscall, prop_dictionary_recv_syscall -- send and receive property
lists to and from the kernel using syscalls
SYNOPSIS
#include <prop/proplib.h>
int
prop_array_send_syscall(prop_array_t array, struct plistref *prefp);
int
prop_array_recv_syscall(const struct plistref *prefp, prop_array_t *arrayp);
int
prop_dictionary_send_syscall(prop_dictionary_t dict, struct plistref *prefp);
int
prop_dictionary_recv_syscall(const struct plistref *prefp, prop_dictionary_t *dictp);
DESCRIPTION
The prop_array_send_syscall, prop_array_recv_syscall, prop_dictionary_send_syscall, and prop_dictionary_recv_syscall functions implement the
user space side of a protocol for sending property lists to and from the kernel using syscall(2).
RETURN VALUES
If successful, functions return zero. Otherwise, an error number is returned to indicate the error.
EXAMPLES
The following (simplified) example demonstrates using prop_dictionary_send_syscall() and prop_dictionary_recv_syscall() in an application:
void
foo_setprops(prop_dictionary_t dict)
{
struct pref pref;
(void) prop_dictionary_send_syscall(dict, &pref);
(void) my_syscall_set(&pref);
}
prop_dictionary_t
foo_getprops(void)
{
prop_dictionary_t dict;
struct pref pref;
(void) my_syscall_get(&pref);
if (prop_dictionary_recv_syscall(&pref, &dict) != 0)
return (NULL);
return (dict);
}
ERRORS
prop_array_send_syscall() and prop_dictionary_send_syscall() will fail if:
[ENOMEM] Cannot allocate memory
[ENOTSUP] Not supported
prop_array_recv_syscall() and prop_dictionary_recv_syscall() will fail if:
[EIO] Input/output error
[ENOTSUP] Not supported
