+.Dt LINK_ADDR 3
+.Os
+.Sh NAME
+.Nm link_addr ,
+.Nm link_ntoa
+.Nd elementary address specification routines for link level access
+.Sh LIBRARY
+.Lb libc
+.Sh SYNOPSIS
+.In sys/types.h
+.In sys/socket.h
+.In net/if_dl.h
+.Ft void
+.Fn link_addr "const char *addr" "struct sockaddr_dl *sdl"
+.Ft char *
+.Fn link_ntoa "const struct sockaddr_dl *sdl"
+.Sh DESCRIPTION
+The routine
+.Fn link_addr
+interprets character strings representing
+link-level addresses, returning binary information suitable
+for use in system calls.
+The routine
+.Fn link_ntoa
+takes
+a link-level
+address and returns an
+.Tn ASCII
+string representing some of the information present,
+including the link level address itself, and the interface name
+or number, if present.
+This facility is experimental and is
+still subject to change.
+.Pp
+For
+.Fn link_addr ,
+the string
+.Fa addr
+may contain
+an optional network interface identifier of the form
+.Dq "name unit-number" ,
+suitable for the first argument to
+.Xr ifconfig 8 ,
+followed in all cases by a colon and
+an interface address in the form of
+groups of hexadecimal digits
+separated by periods.
+Each group represents a byte of address;
+address bytes are filled left to right from
+low order bytes through high order bytes.
+.Pp
+.\" A regular expression may make this format clearer:
+.\" .Bd -literal -offset indent
+.\" ([a-z]+[0-9]+:)?[0-9a-f]+(\e.[0-9a-f]+)*
+.\" .Ed
+.\" .Pp
+Thus
+.Li le0:8.0.9.13.d.30
+represents an ethernet address
+to be transmitted on the first Lance ethernet interface.
+.Pp
+The direct use of these functions is deprecated in favor of the
+.Xr addr2ascii 3
+interface; however, portable programs cannot rely on the latter as it is
+not yet widely implemented.
+.Sh RETURN VALUES
+The
+.Fn link_ntoa
+function
+always returns a null terminated string.
+The
+.Fn link_addr
+function
+has no return value.
+(See
+.Sx BUGS . )
+.Sh SEE ALSO
+.Xr addr2ascii 3
+.\" .Xr iso 4
+.Sh HISTORY
+The
+.Fn link_addr
+and
+.Fn link_ntoa
+functions appeared in
+.Bx 4.3 Reno .
+.Sh BUGS
+The returned values for link_ntoa
+reside in a static memory area.
+.Pp
+The function
+.Fn link_addr
+should diagnose improperly formed input, and there should be an unambiguous
+way to recognize this.
+.Pp
+If the
+.Va sdl_len
+field of the link socket address
+.Fa sdl
+is 0,
+.Fn link_ntoa
+will not insert a colon before the interface address bytes.
+If this translated address is given to
+.Fn link_addr
+without inserting an initial colon,
+the latter will not interpret it correctly.

+.Dt STRMODE 3
+.Os
+.Sh NAME
+.Nm strmode
+.Nd convert inode status information into a symbolic string
+.Sh LIBRARY
+.Lb libc
+.Sh SYNOPSIS
+.In string.h
+.Ft void
+.Fn strmode "mode_t mode" "char *bp"
+.Sh DESCRIPTION
+The
+.Fn strmode
+function
+converts a file
+.Fa mode
+(the type and permission information associated with an inode, see
+.Xr stat 2 )
+into a symbolic string which is stored in the location referenced by
+.Fa bp .
+This stored string is eleven characters in length plus a trailing
+.Dv NUL .
+.Pp
+The first character is the inode type, and will be one of the following:
+.Pp
+.Bl -tag -width flag -offset indent -compact
+.It \-
+regular file
+.It b
+block special
+.It c
+character special
+.It d
+directory
+.It l
+symbolic link
+.It p
+fifo
+.It s
+socket
+.It w
+whiteout
+.It ?
+unknown inode type
+.El
+.Pp
+The next nine characters encode three sets of permissions, in three
+characters each.
+The first three characters are the permissions for the owner of the
+file, the second three for the group the file belongs to, and the
+third for the ``other'', or default, set of users.
+.Pp
+Permission checking is done as specifically as possible.
+If read permission is denied to the owner of a file in the first set
+of permissions, the owner of the file will not be able to read the file.
+This is true even if the owner is in the file's group and the group
+permissions allow reading or the ``other'' permissions allow reading.
+.Pp
+If the first character of the three character set is an ``r'', the file is
+readable for that set of users; if a dash ``\-'', it is not readable.
+.Pp
+If the second character of the three character set is a ``w'', the file is
+writable for that set of users; if a dash ``\-'', it is not writable.
+.Pp
+The third character is the first of the following characters that apply:
+.Bl -tag -width xxxx
+.It S
+If the character is part of the owner permissions and the file is not
+executable or the directory is not searchable by the owner, and the
+set-user-id bit is set.
+.It S
+If the character is part of the group permissions and the file is not
+executable or the directory is not searchable by the group, and the
+set-group-id bit is set.
+.It T
+If the character is part of the other permissions and the file is not
+executable or the directory is not searchable by others, and the ``sticky''
+.Pq Dv S_ISVTX
+bit is set.
+.It s
+If the character is part of the owner permissions and the file is
+executable or the directory searchable by the owner, and the set-user-id
+bit is set.
+.It s
+If the character is part of the group permissions and the file is
+executable or the directory searchable by the group, and the set-group-id
+bit is set.
+.It t
+If the character is part of the other permissions and the file is
+executable or the directory searchable by others, and the ``sticky''
+.Pq Dv S_ISVTX
+bit is set.
+.It x
+The file is executable or the directory is searchable.
+.It \-
+None of the above apply.
+.El
+.Pp
+The last character is a plus sign ``+'' if any there are any alternate
+or additional access control methods associated with the inode, otherwise
+it will be a space.
