descriptors against -1 (as appropriate).
* add actual checks which to detect stuff that would trigger_DIAGASSERT(),
and attempt to return a sane error condition.
* knf some code
* remove some `register' decls.
the first two items result in the addition of code similar to the
following in various functions:
_DIAGASSERT(path != NULL)
#ifdef _DIAGNOSTIC
if (path == NULL) {
errno = EFAULT;
return (-1);
}
#endif
* add support for YP "master.passwd.by*" (master.passwd in YP, including
pw_passwd) and "passwd.adjunct.by*" (SunOS `secure' maps (?)), based
on code in FreeBSD and partially from OpenBSD.
this is only used if euid == 0.
with this, the YP "passwd.by*" maps can have `*' in the pw_passwd field.
* use pw_scan() to parse YP "passwd.by*" and "master.passwd.by*" entries
XXX: i didn't test the "passwd.adjunct" support...
