NAME

  inet6_rth_getaddr - Retrieve an address for an index from an IPv6 Routing
  header


SYNOPSIS

  #include <netinet/ip6.h>

  struct in6_addr *inet6_rth_getaddr(
	  const void *bp,
	  int index );


LIBRARY

  Standard C Library (libc)


PARAMETERS

  bp  Points to a buffer that contains an IPv6 Routing header.

  index
      Specifies a value that identifies a position in a Routing header for a
      specific address. Valid values range from 0 to the return value from
      inet6_rth_segments() minus 1.


DESCRIPTION

  The inet6_rth_getaddr() function uses a specified index value and retrieves
  a pointer to an address in a Routing header specified by bp. Call
  inet6_rth_segments() before calling this function in order to determine the
  number of segments (addresses) in the Routing header.


RETURN VALUES

  Upon successful completion, the inet6_rth_getaddr() function returns a
  pointer to an address. Upon failure, it returns a NULL pointer.
