A zero result value mans that no error occurred; we know for certain
that the user exists or does not exist.
That's almost consistent with, for example, the XOPEN standard: \
The getpwnam_r() function shall return zero on success or if
the requested entry was not found AND NO ERROR HAS OCCURRED.
If an error has occurred, an error number shall be returned to
indicate the error.
What bugs me is the text that follows later in that same Linux
manpage:
ERRORS
0 or ENOENT or ESRCH or EBADF or EPERM or ...
The given name or uid was not found.
This text makes no sense. It is in conflict with XOPEN, and with
the other quote from the Linux manpage.
