Currently, the dommigrate example returns 0 or 1 for success or failure state, respectively. Except for a few cases where it forgot to change the @ret variable just before jumping onto the 'cleanup' label. Making the code follow our usual pattern (initialize @ret to an error value and set it to success value only at the end) fixes those cases. Also, using EXIT_SUCCESS and EXIT_FAILURE is more portable (even though on my system they are just an alias to values the example already uses).
