MAC_FREE(3) BSD Library Functions Manual MAC_FREE(3)NAMEmac_free -- free MAC labelLIBRARYStandard C Library (libc, -lc)SYNOPSIS#include <sys/mac.h> int mac_free(mac_t label);DESCRIPTIONThe mac_free() function frees the storage allocated to contain a mac_t.RETURN VALUESThe mac_free() function always returns 0. WARNING: see the notes in the BUGS section regarding the use of this function.SEE ALSOmac(3), mac_get(3), mac_prepare(3), mac_set(3), mac_text(3), posix1e(3), mac(4), mac(9)STANDARDSPOSIX.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.HISTORYSupport for Mandatory Access Control was introduced in FreeBSD 5.0 as part of the TrustedBSD Project.BUGSPOSIX.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.BSDDecember 21, 2001 BSD
