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


       ENOMEM An attempt to allocate memory failed.
