- Add man page sections '(N)' to external references, and '()' on
functions described in the same man page.
- Escape minus signs when those are expected to be used on the command
line or files.
- Mark files and variables in italic; Note headings, function names,
constants, program options and man page references in bold.
- Do not justify and hyphenate SEE ALSO section, and avoid hyphenation
on symbol names by prepending them with \%.
- Remove trailing dot from NAME section description.
- Split sections with a no-op command '.', to visually distinguish them
but to avoid introducing spurious vertical space in the formatted
output.
- Add explicit .sp commands in the SYNOPSIS section between function
prototypes, and fix space placement in function protoypes.
- Split header includes with .br (instead of the explicit or implicit
.sp) so that they are vertically contiguous.
- Add missing {} around SELINUXTYPE and POLICYTYPE variable text in
paths.
- Remove unneeded formatting commands.
- Remove spurious blank lines.

.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.
