Unix standards specify a zero ("0") exit status for successful execution of an
application, non-zero otherwise.  The meaning of any specific non-zero value
is up to the application developer(s).

The value to which errno is set is not related to the exit status (aka return 
code)
of an application.  errno is intended to be used internally in the C code, and
any similiarity between it an the exit status is coincidence (or the application
developer's idea of an ordered world).
