WARNING: see the notes in the .Sx BUGS section regarding the use of this function. .Sh SEE ALSO .Xr mac 3 , .Xr mac_get 3 , .Xr mac_prepare 3 , .Xr mac_set 3 , .Xr mac_text 3 , .Xr posix1e 3 , .Xr mac 4 , .Xr mac 9 .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 .Fx POSIX.1e implementation page for more information. .Sh HISTORY Support for Mandatory Access Control was introduced in .Fx 5.0 as part of the .Tn TrustedBSD Project. .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 implementation, .Fn mac_free is specific to .Vt mac_3 , and must not be used to free the character strings returned from .Fn mac_to_text . Doing so may result in undefined behavior.
