NAME         top

       security_class_to_string, security_av_perm_to_string,
       string_to_security_class, string_to_av_perm, security_av_string,
       mode_to_security_class - convert between SELinux class and
       permission values and string names.  print_access_vector -
       display an access vector in human-readable form.

SYNOPSIS         top

       #include <selinux/selinux.h>

       const char *security_class_to_string(security_class_t tclass);

       const char *security_av_perm_to_string(security_class_t tclass,
       access_vector_t av);

       int security_av_string(security_class_t tclass, access_vector_t
       av, char **result);

       security_class_t string_to_security_class(const char *name);

       security_class_t mode_to_security_class(mode_t mode);

       access_vector_t string_to_av_perm(security_class_t tclass, const
       char *name);

       void print_access_vector(security_class_t tclass, access_vector_t
       av);

DESCRIPTION         top

       security_class_to_string() returns a string name for class
       tclass, or NULL if the class is invalid.  The returned string
       must not be modified or freed.

       security_av_perm_to_string() returns a string name for the access
       vector bit av of class tclass, or NULL if either argument is
       invalid.  The returned string must not be modified or freed.

       security_av_string() computes a full access vector string
       representation using tclass and av, which may have multiple bits
       set.  The string is returned in the memory pointed to by result,
       and should be freed by the caller using free(3).

       string_to_security_class() returns the class value corresponding
       to the string name name, or zero if no such class exists.

       mode_to_security_class() returns the class value corresponding to
       the specified mode, or zero if no such class exists.

       string_to_av_perm() returns the access vector bit corresponding
       to the string name name and security class tclass, or zero if no
       such value exists.

       print_access_vector() displays an access vector in human-readable
       form on the standard output stream.

RETURN VALUE         top

       security_av_string() returns zero on success or -1 on error with
       errno set appropriately.  print_access_vector() does not return a
       value. All other functions return zero or NULL on error.

ERRORS         top

       EINVAL A class or access vector argument is not recognized by the
              currently loaded policy.

       ENOMEM An attempt to allocate memory failed.
