Return codes suggest to Asterisk how to handle the exit of the application.
There are really only two useful states:

0: application returned normally, Asterisk continues through the dialplan.
non-zero: application returned with a fault, Asterisk hangs up the channel.

By convention, most applications in Asterisk which return non-zero return -1.

If you wish to return a meaningful value from your application, I suggest that
you set a channel variable at the conclusion of your application, before
returning 0.
