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.

const char *security_class_to_string(security_class_t

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.
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.
- EINVAL
- A class or access vector argument is not recognized by the
currently loaded policy.
- ENOMEM
- An attempt to allocate memory failed.
