MAC_FREE(3)            FreeBSD Library Functions Manual            MAC_FREE(3)

NAME
     mac_free - free MAC label

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <sys/mac.h>

     int
     mac_free(mac_t label);

DESCRIPTION
     The mac_free() function frees the storage allocated to contain a mac_t.

RETURN VALUES
     The mac_free() function always returns 0.  WARNING: see the notes in the
     BUGS section regarding the use of this function.

SEE ALSO
     mac(3), mac_get(3), mac_prepare(3), mac_set(3), mac_text(3), posix1e(3),
     mac(4), mac(9)

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 FreeBSD POSIX.1e implementation page for more
     information.

HISTORY
     Support for Mandatory Access Control was introduced in FreeBSD 5.0 as
     part of the TrustedBSD Project.

BUGS
     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 mac_3, and must
     not be used to free the character strings returned from mac_to_text().
     Doing so may result in undefined behavior.
