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.
