.Sh STANDARDS
POSIX.1e is described in IEEE POSIX.1e draft 17.
Discussion of the draft
continues on the cross-platform POSIX.1e implementation mailing list.
To join this list, see the

POSIX.1e implementation page
for more information.

as part of the

.Sh BUGS
POSIX.1e specifies that
.Fn mac_free
will be used to free text strings created using
.Xr mac_to_text 3 .
Because
.Vt mac_t

is a complex structure in the
.Tn TrustedBSD

2002-10-24 01:01:29 +00:00
.Fn mac_free
is specific to that type, and must not be used to free the character
strings returned from
.Fn mac_to_text .
Doing so may result in undefined behavior,
including application failure.
