I believe this depends on the function in question. Indeed, UN*X
conventions (especially for shell scripts) do usually dictate a 0 value
upon successful completion, but many C functions (eg. fopen()) return
NULL upon an error and set errno. I suppose for a main function, a
return value of 0 would be more usual as it is most likely to be tested
in a 'driver-script' which should follow the conventions. But I think
this debate is derivative to the original question; the point is, SOME
value should be returned.
