unsetting OPTINT in getopts

i am calling a function multiple time which uses getopts to parse function arguments.
WHile running, i am getting a bad shift error. i read somewhere that we have to reset the OPTIND variable after each getopts call. how do we do it?
using unset OPTIND doesn't helpSmilie

If you want to reset it, you don't want to unset it:

Code:
OPTIND=1

when ever shell invokes OPTIND is initialized to 1
since you are calling function many times in same shell you are getting that error
so as cfajohnson suggested set OPTIND to in at the starting of function
