DESCRIPTION

31       security_class_to_string returns a string name  for  class  tclass,  or
32       NULL if the class is invalid.  The returned string must not be modified
33       or freed.
34
35       security_av_perm_to_string returns a string name for the access  vector
36       bit  av  of  class  tclass, or NULL if either argument is invalid.  The
37       returned string must not be modified or freed.
38
39       security_av_string computes a full access vector string  representation
40       using  tclass  and av, which may have multiple bits set.  The string is
41       returned in the memory pointed to by result, and should be freed by the
42       caller using free(3).
43
44       string_to_security_class  returns  the class value corresponding to the
45       string name name, or zero if no such class exists.
46
47       string_to_av_perm returns the access vector bit  corresponding  to  the
48       string  name  name  and security class tclass, or zero if no such value
49       exists.

RETURN VALUE

53       security_av_string returns returns zero on success or -1 on error  with
54       errno  set  appropriately.   All other functions return zero or NULL on
55       error.

ERRORS

59       EINVAL A class or access vector argument is not recognized by the  cur‐
60              rently loaded policy.
61
62
63       ENOMEM An attempt to allocate memory failed.
