Example:
$ cat show1.ksh
#! /bin/ksh
function exitfunc { echo retcode of last cmd: $1 ; }
trap 'exitfunc $? ' EXIT
false
$ ./show2.ksh
retcode of last cmd: 1

$ cat show2.ksh
#! /bin/ksh
function exitfunc { echo retcode of last cmd: $1 ; }
trap 'exitfunc $? ' EXIT
true
$ ./show2.ksh
retcode of last cmd: 0
