mac_prepare(mac_t
*mac, const char
*elements);

mac_prepare_type(mac_t

The mac_prepare family of functions
allocates the appropriate amount of storage and initializes
*mac for use by
mac_get(3). When the
resulting label is passed into the
mac_get(3) functions,
the kernel will attempt to fill in the label elements specified when the
label was prepared. Elements are specified in a nul-terminated string, using
commas to delimit fields. Element names may be prefixed with the
‘?’ character to indicate that a
failure by the kernel to retrieve that element should not be considered
fatal.
The
mac_prepare()
function accepts a list of policy names as a parameter, and allocates the
storage to fit those label elements accordingly. The remaining functions in
the family make use of system defaults defined in
mac.conf(5) instead of
an explicit elements argument, deriving the default
from the specified object type.
mac_prepare_type()
allocates the storage to fit an object label of the type specified by the
name argument. The
mac_prepare_file_label(),
mac_prepare_ifnet_label(),
and
mac_prepare_process_label()
functions are equivalent to invocations of
mac_prepare_type() with arguments of
"file", "ifnet", and "process"
respectively.
Upon successful completion, the value 0 is returned; otherwise the value -1 is returned and the global variable errno is set to indicate the error.

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.
Support for Mandatory Access Control was introduced in FreeBSD 5.0 as part of the TrustedBSD Project. Support for generic object types first appeared in FreeBSD 5.2.
