inet6_rth_reverse()--Reverse the Order of Addresses in the IPv6 Routing Header

Syntax

  #include <netinet/in.h>

  int inet6_rth_reverse(const void *in,
                        void *out)

  Service Program Name: QSOSRV1IP6

  Default Public Authority: *USE

  Threadsafe: Yes

The inet6_rth_reverse() function reads a routing extension header and writes a new routing extension header with the addresses in reverse order.

Parameters

in: (Input) Pointer to a buffer that contains the routing extension header.
out: (I/O) Pointer to a buffer to store the new routing extension header with reverse addresses.

No authorization is required.

inet6_rth_reverse() returns an integer. Possible values are:

When inet6_rth_reverse() fails, errno can be set to one of the following:

[EFAULT]

Bad address.

The system detected an address that was not valid while attempting to access the buffer pointed to by the in or out parameter.

The in and out parameters can point to the same buffer.
The ip6r_segleft member in the ip6_rthdr structure will be set to the number of segments in the new header.
This function can be used to send datagram packets along the reverse route of the packets received.

inet6_rth_add()--Add an IPv6 Address to the IPv6 Routing Header
inet6_rth_getaddr()--Retrieve an Address from the IPv6 Routing Header
inet6_rth_init()--Initialize Buffer Data for the IPv6 Routing Header
inet6_rth_segments()--Return the Number of Segments in the IPv6 Routing Header
inet6_rth_space()--Return the Number of Bytes Required for the IPv6 Routing Header
