Hi,
just saw that cat's *main* function does never return even though there is a
return value,
exit(3) is called instead.
Is there any reason why or is it just historically, cause it's a bit confusing?
If exit(3) is always called, than why not changing the return value to *void*?
Other calls in *src/bin/* share the same behavior.
Regards,
--F.
