mac_free

MAC_FREE(3)						   BSD 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.
