NAME
       security_class_to_string,  security_av_perm_to_string,  string_to_secu‐
       rity_class, string_to_av_perm,  security_av_string  -  convert  between
       SELinux class and permission values and string names.

SYNOPSIS
       #include <selinux/selinux.h>

       #include <selinux/flask.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);

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

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.

       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.

RETURN VALUE
       security_av_string returns returns zero on success or -1 on error  with
       errno  set  appropriately.   All other functions return zero or NULL on
       error.

ERRORS
       EINVAL A class or access vector argument is not recognized by the  cur‐
	      rently loaded policy.

       ENOMEM An attempt to allocate memory failed.
