Returns a pointer to a specific IPv6 address in a Routing header.
The inet6_rth_getaddr subroutine returns a pointer to the IPv6 address specified by index in the Routing header described by bp. An application should first call inet6_rth_segments() to obtain the number of segments in the Routing header.
