.SH "DESCRIPTION"
|
|
.BR security_class_to_string ()
|
|
returns a string name for class
|
|
.IR tclass ,
|
|
or NULL if the class is invalid. The returned string must not be modified or freed.
|
|
|
|
.BR security_av_perm_to_string ()
|
|
returns a string name for the access vector bit
|
|
.I av
|
|
of class
|
|
.IR tclass ,
|
|
or NULL if either argument is invalid. The returned string must not be modified or freed.
|
|
|
|
.BR security_av_string ()
|
|
computes a full access vector string representation using
|
|
.I tclass
|
|
and
|
|
.IR av ,
|
|
which may have multiple bits set. The string is returned in the memory pointed to by
|
|
.IR result ,
|
|
and should be freed by the caller using
|
|
.BR free (3).
|
|
|
|
.BR string_to_security_class ()
|
|
returns the class value corresponding to the string name
|
|
.IR name ,
|
|
or zero if no such class exists.
|
|
|
|
.BR mode_to_security_class ()
|
|
returns the class value corresponding to the specified
|
|
.IR mode ,
|
|
or zero if no such class exists.
|
|
|
|
.BR string_to_av_perm ()
|
|
returns the access vector bit corresponding to the string name
|
|
.I name
|
|
and security class
|
|
.IR tclass ,
|
|
or zero if no such value exists.
|
|
|
|
.BR print_access_vector ()
|
|
displays an access vector in human-readable form on the standard output
|
|
stream.
|
|
.
|
|
.SH "RETURN VALUE"
|
|
.BR security_av_string ()
|
|
returns zero on success or \-1 on error with
|
|
.I errno
|
|
set appropriately.
|
|
.BR print_access_vector ()
|
|
does not return a value. All other functions return zero or NULL on error.
|
|
.
|
|
.SH "ERRORS"
|
|
.TP
|
|
.B EINVAL
|
|
A class or access vector argument is not recognized by the currently loaded policy.
|
|
|
|
.TP
|
|
.B ENOMEM
|
|
An attempt to allocate memory failed.
