30/* Load a source policy into p. policydb_init will called within this function.
31 *
32 * Example: test_load_policy(p, POLICY_BASE, 1, "foo", "base.conf") will load the
33 *  policy "policies/foo/mls/base.conf" into p.
34 *
35 * Arguments:
36 *  p            policydb_t into which the policy will be read. This should be
37 *                malloc'd but not passed to policydb_init.
38 *  policy_type  Type of policy expected - POLICY_BASE or POLICY_MOD.
39 *  mls          Boolean value indicating whether an mls policy is expected.
40 *  test_name    Name of the test which will be the name of the directory in
41 *                which the policies are stored.
42 *  policy_name  Name of the policy in the directory.
43 *
44 * Returns:
45 *  0            success
46 * -1            error - the policydb will be destroyed but not freed.
