MAC_PREPARE(3)						   BSD Library Functions Manual 					    MAC_PREPARE(3)

NAME

     mac_prepare, mac_prepare_type, mac_prepare_file_label, mac_prepare_ifnet_label, mac_prepare_process_label -- allocate appropriate storage for
     mac_t

SYNOPSIS

     #include <sys/mac.h>

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

     int
     mac_prepare_type(mac_t *mac, const char *name);

     int
     mac_prepare_file_label(mac_t *mac);

     int
     mac_prepare_ifnet_label(mac_t *mac);

     int
     mac_prepare_process_label(mac_t *mac);

DESCRIPTION

     The mac_prepare family of functions allocates the appropriate amount of storage and initializes *mac for use by mac_get(3).  When the result-
     ing label is passed into the mac_get(3) functions, the kernel will attempt to fill in the label elements specified when the label was pre-
     pared.  Elements are specified in a nul-terminated string, using commas to delimit fields.  Element names may be prefixed with the '?' char-
     acter 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.

RETURN VALUES

     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.
