The mac_free() function always returns 0. WARNING: see the notes in the

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

Support for Mandatory Access Control was introduced in FreeBSD 5.0 as
part of the TrustedBSD Project.
POSIX.1e specifies that mac_free() will be used to free text strings created
using mac_to_text(3). Because mac_t is a complex structure in the
TrustedBSD implementation, mac_free() is specific to that type, and must
not be used to free the character strings returned from mac_to_text().
Doing so may result in undefined behavior, including application failure.
