+.Os
+.Sh NAME
+.Nm getifmaddrs
+.Nd get multicast group memberships
+.Sh SYNOPSIS
+.In sys/types.h
+.In sys/socket.h
+.In ifaddrs.h
+.Ft int
+.Fn getifmaddrs "struct ifmaddrs **ifmap"
+.Ft void
+.Fn freeifmaddrs "struct ifmaddrs *ifmp"
+.Sh DESCRIPTION
+The
+.Fn getifmaddrs
+function stores a reference to a linked list of the multicast memberships
+on the local machine in the memory referenced by
+.Fa ifmap .
+The list consists of
+.Vt ifmaddrs
+structures, as defined in the include file
+.In ifaddrs.h .
+The
+.Vt ifmaddrs
+structure contains at least the following entries:
+.Bd -literal
+ struct ifmaddrs *ifma_next; /* Pointer to next struct */
+ struct sockaddr *ifma_name; /* Interface name (AF_LINK) */
+ struct sockaddr *ifma_addr; /* Multicast address */
+ struct sockaddr *ifma_lladdr; /* Link-layer translation, if any */
+.Ed
+.Pp
+The
+.Va ifma_next
+field contains a pointer to the next structure on the list.
+This field is
+.Dv NULL
+in last structure on the list.
+.Pp
+The
+.Va ifma_name
+field references an
+.Dv AF_LINK
+address structure, containing the name of the
+interface where the membership exists.
+.Pp
+The
+.Va ifma_addr
+references the address that this membership is for.
+.Pp
+The
+.Va ifma_lladdr
+field references a link-layer translation for the protocol-level address in
+.Va ifma_addr ,
+if one is set, otherwise it is
+.Dv NULL .
+.Pp
+The data returned by
+.Fn getifmaddrs
+is dynamically allocated and should be freed using
+.Fn freeifmaddrs
+when no longer needed.
+.Sh RETURN VALUES
+.Rv -std getifmaddrs
+.Sh ERRORS
+The
+.Fn getifmaddrs
+may fail and set
+.Va errno
+for any of the errors specified for the library routines
+.Xr malloc 3
+or
+.Xr sysctl 3 .
+.Sh SEE ALSO
+.Xr sysctl 3 ,
+.Xr networking 4 ,
+.Xr ifconfig 8
+.Sh HISTORY
+The
+.Fn getifmaddrs
+function first appeared in
+.Fx 5.2 .
+.Sh BUGS
+If both
+.In net/if.h
+and
+.In ifaddrs.h
+are being included,
+.In net/if.h
+.Em must
+be included before
+.In ifaddrs.h .

+.\"
+.Sh DESCRIPTION
+Building and parsing the Hop-by-Hop and Destination options is
+complicated.
+The advanced sockets API defines a set of functions to
+help applications create and manipulate Hop-by-Hop and Destination
+options.
+This man page describes the functions specified in
+IETF Draft RFC3542.
+These functions use the
+formatting rules specified in Appendix B in RFC2460, i.e., that the
+largest field is placed last in the option.
+The function prototypes
+for these functions are all contained in the
+.In netinet/in.h
+header file.
+.\"
+.Ss inet6_opt_init
+The
+.Fn inet6_opt_init
+function
+returns the number of bytes needed for an empty
+extension header, one without any options.
+If the
+.Fa extbuf
+argument points to a valid section of memory
+then the
+.Fn inet6_opt_init
+function also initializes the extension header's length field.
+When attempting to initialize an extension buffer passed in the
+.Fa extbuf
+argument,
+.Fa extlen
+must be a positive multiple of 8 or else the function fails and
+returns \-1 to the caller.
+.\"
+.Ss inet6_opt_append
+The
+.Fn inet6_opt_append
+function can perform two different jobs.
+When a valid
+.Fa extbuf
+argument is supplied it appends an option to the extension buffer and
+returns the updated total length as well as a pointer to the newly
+created option in
+.Fa databufp .
+If the value
+of
+.Fa extbuf
+is
+.Dv NULL
+then the
+.Fn inet6_opt_append
+function only reports what the total length would
+be if the option were actually appended.
+The
+.Fa len
+and
+.Fa align
+arguments specify the length of the option and the required data
+alignment which must be used when appending the option.
+The
+.Fa offset
+argument should be the length returned by the
+.Fn inet6_opt_init
+function or a previous call to
+.Fn inet6_opt_append .
+.Pp
+The
+.Fa type
+argument is the 8-bit option type.
+.Pp
+After
+.Fn inet6_opt_append
+has been called, the application can use the buffer pointed to by
+.Fa databufp
+directly, or use
+.Fn inet6_opt_set_val
+to specify the data to be contained in the option.
+.Pp
+Option types of
+.Li 0
+and
+.Li 1
+are reserved for the
+.Li Pad1
+and
+.Li PadN
+options.
+All other values from 2 through 255 may be used by applications.
+.Pp
+The length of the option data is contained in an 8-bit value and so
+may contain any value from 0 through 255.
+.Pp
+The
+.Fa align
+parameter must have a value of 1, 2, 4, or 8 and cannot exceed the
+value of
+.Fa len .
+The alignment values represent no alignment, 16 bit, 32 bit and 64 bit
+alignments, respectively.
+.\"
+.Ss inet6_opt_finish
+The
+.Fn inet6_opt_finish
+function
+calculates the final padding necessary to make the extension header a
+multiple of 8 bytes, as required by the IPv6 extension header
+specification, and returns the extension header's updated total
+length.
+The
+.Fa offset
+argument should be the length returned by
+.Fn inet6_opt_init
+or
+.Fn inet6_opt_append .
+When
+.Fa extbuf
+is not
+.Dv NULL
+the function also sets up the appropriate padding bytes by inserting a
+Pad1 or PadN option of the proper length.
+.Pp
+If the extension header is too small to contain the proper padding
+then an error of \-1 is returned to the caller.
+.\"
+.Ss inet6_opt_set_val
+The
+.Fn inet6_opt_set_val
+function inserts data items of various sizes into the data portion of
+the option.
+The
+.Fa databuf
+argument is a pointer to memory that was returned by the
+.Fn inet6_opt_append
+call and the
+.Fa offset
+argument specifies where the option should be placed in the
+data buffer.
+The
+.Fa val
+argument points to an area of memory containing the data to be
+inserted into the extension header, and the
+.Fa vallen
+argument indicates how much data to copy.
+.Pp
+The caller should ensure that each field is aligned on its natural
+boundaries as described in Appendix B of RFC2460.
+.Pp
+The function returns the offset for the next field which is calculated as
+.Fa offset
++
+.Fa vallen
+and is used when composing options with multiple fields.
+.\"
+.Ss inet6_opt_next
+The
+.Fn inet6_opt_next
+function parses received extension headers.
+The
+.Fa extbuf
+and
+.Fa extlen
+arguments specify the location and length of the extension header
+being parsed.
+The
+.Fa offset
+argument should either be zero, for the first option, or the length value
+returned by a previous call to
+.Fn inet6_opt_next
+or
+.Fn inet6_opt_find .
+The return value specifies the position where to continue scanning the
+extension buffer.
+The option is returned in the arguments
+.Fa typep , lenp ,
+and
+.Fa databufp ,
+which
+point to the 8-bit option type, the 8-bit option length and the option
+data, respectively.
+This function does not return any PAD1 or PADN options.
+When an error occurs or there are no more options, the return
+value is \-1.
+.\"
+.Ss inet6_opt_find
+The
+.Fn inet6_opt_find
+function searches the extension buffer for a particular option type,
+passed in through the
+.Fa type
+argument.
+If the option is found then the
+.Fa lenp
+and
+.Fa databufp
+arguments are updated to point to the option's length and data,
+respectively.
+The
+.Fa extbuf
+and
+.Fa extlen
+arguments
+must point to a valid extension buffer and give its length.
+The
+.Fa offset
+argument can be used to search from a location anywhere in the
+extension header.
+.Ss inet6_opt_get_val
+The
+.Fn inet6_opt_get_val
+function extracts data items of various sizes in the data portion of
+the option.
+The
+.Fa databuf
+is a pointer returned by the
+.Fn inet6_opt_next
+or
+.Fn inet6_opt_find
+functions.
+The
+.Fa val
+argument points where the data will be extracted.
+The
+.Fa offset
+argument specifies from where in the data portion of the option the
+value should be extracted; the first byte of option data is specified
+by an offset of zero.
+.Pp
+It is expected that each field is aligned on its natural boundaries as
+described in Appendix B of RFC2460.
+.Pp
+The function returns the offset for the next field
+by calculating
+.Fa offset
++
+.Fa vallen
+which can be used when extracting option content with multiple fields.
+Robust receivers must verify alignment before calling this function.
+.\"
+.Sh RETURN VALUES
+All the functions return
+\-1
+on an error.

+.Sh DESCRIPTION
+The IPv6 Advanced API, RFC 3542, defines the functions that an
+application calls to build and examine IPv6 Routing headers.
+Routing headers are used to perform source routing in IPv6 networks.
+The RFC uses the word
+.Dq segments
+to describe addresses and that is the term used here as well.
+All of the functions are defined in the
+.In netinet/in.h
+header file.
+The functions described in this manual page all operate
+on routing header structures which are defined in
+.In netinet/ip6.h
+but which should not need to be modified outside the use of this API.
+The size and shape of the route header structures may change, so using
+the APIs is a more portable, long term, solution.
+.Pp
+The functions in the API are split into two groups, those that build a
+routing header and those that parse a received routing header.
+We will describe the builder functions followed by the parser functions.
+.Ss inet6_rth_space
+The
+.Fn inet6_rth_space
+function returns the number of bytes required to hold a Routing Header
+of the type, specified in the
+.Fa type
+argument and containing the number of addresses specified in the
+.Fa segments
+argument.
+When the type is
+.Dv IPV6_RTHDR_TYPE_0
+the number of segments must be from 0 through 127.
+Routing headers of type
+.Dv IPV6_RTHDR_TYPE_2
+contain only one segment, and are only used with Mobile IPv6.
+The return value from this function is the number of bytes required to
+store the routing header.
+If the value 0 is returned then either the
+route header type was not recognized or another error occurred.
+.Ss inet6_rth_init
+The
+.Fn inet6_rth_init
+function initializes the pre-allocated buffer pointed to by
+.Fa bp
+to contain a routing header of the specified type The
+.Fa bp_len
+argument is used to verify that the buffer is large enough.
+The caller must allocate the buffer pointed to by bp.
+The necessary buffer size should be determined by calling
+.Fn inet6_rth_space
+described in the previous sections.
+.Pp
+The
+.Fn inet6_rth_init
+function returns a pointer to
+.Fa bp
+on success and
+.Dv NULL
+when there is an error.
+.Ss inet6_rth_add
+The
+.Fn inet6_rth_add
+function adds the IPv6 address pointed to by
+.Fa addr
+to the end of the routing header being constructed.
+.Pp
+A successful addition results in the function returning 0, otherwise
+\-1 is returned.
+.Ss inet6_rth_reverse
+The
+.Fn inet6_rth_reverse
+function takes a routing header, pointed to by the
+argument
+.Fa in ,
+and writes a new routing header into the argument pointed to by
+.Fa out .
+The routing header at that sends datagrams along the reverse of that
+route.
+Both arguments are allowed to point to the same buffer meaning
+that the reversal can occur in place.
+.Pp
+The return value of the function is 0 on success, or \-1 when
+there is an error.
+.\"
+.Pp
+The next set of functions operate on a routing header that the
+application wants to parse.
+In the usual case such a routing header
+is received from the network, although these functions can also be
+used with routing headers that the application itself created.
+.Ss inet6_rth_segments
+The
+.Fn inet6_rth_segments
+function returns the number of segments contained in the
+routing header pointed to by
+.Fa bp .
+The return value is the number of segments contained in the routing
+header, or \-1 if an error occurred.
+It is not an error for 0 to be
+returned as a routing header may contain 0 segments.
+.\"
+.Ss inet6_rth_getaddr
+The
+.Fn inet6_rth_getaddr
+function is used to retrieve a single address from a routing header.
+The
+.Fa index
+is the location in the routing header from which the application wants
+to retrieve an address.
+The
+.Fa index
+parameter must have a value between 0 and one less than the number of
+segments present in the routing header.
+The
+.Fn inet6_rth_segments
+function, described in the last section, should be used to determine
+the total number of segments in the routing header.
+The
+.Fn inet6_rth_getaddr
+function returns a pointer to an IPv6 address on success or
+.Dv NULL
+when an error has occurred.
+.\"
+.Sh EXAMPLES
+RFC 3542 gives extensive examples in Section 21, Appendix B.
+.Pp
+KAME also provides examples in the advapitest directory of its kit.
+.\"
+.Sh DIAGNOSTICS
+The
+.Fn inet6_rth_space
+and
+.Fn inet6_rth_getaddr
+functions return 0 on errors.
+.Pp
+The
+.Fn inet6_rthdr_init
+function returns
+.Dv NULL
+on error.
+The
+.Fn inet6_rth_add
+and
+.Fn inet6_rth_reverse
+functions return 0 on success, or \-1 upon an error.

.Sh DESCRIPTION
Users and groups can be referred to in multiple ways.
In addition to the traditional uid and gid,
.Pp
.Fn mbr_sid_to_uuid
takes a sid and returns the associated uuid.
-Like
-.Fn mbr_uuid_to_id ,
-.Fn mbr_sid_to_uuid
-always returns a uuid for the sid, even if the sid can not be found.
.Pp
.Fn mbr_uuid_to_sid
returns a sid for the associated uuid.
+.Pp
+Two additional utility functions are available to convert between sids and a string representation.
+String representations may be required, for example, when text files or XML files are used to save sid values.
+.Pp
+.Fn mbr_sid_to_string
+converts a sid into a string representation.
+The
+.Fa string
+parameter must be a buffer of at least 194 characters.
+The converted string is terminated with a nul character.
+.Pp
+.Fn mbr_string_to_sid
+converts an external string representation into a sid.
.Sh RETURN VALUES
These functions return 0 on success, or EIO if communications with the
.Xr DirectoryService 8
and
.Fn mbr_uid_to_uuid
