inet6_rth_reverse(3)


NAME

  inet6_rth_reverse - Reverse the order of addresses in an IPv6 Routing
  header


SYNOPSIS

  #include <netinet/ip6.h>

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


LIBRARY

  Standard C Library (libc)


PARAMETERS

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

  out Points to a buffer that is to contain the Routing header with the
      reversed addresses. This parameter can point to the same buffer
      specified by in.


DESCRIPTION

  The inet6_rth_reverse() function reads an IPv6 Routing header and writes a
  new Routing header, reversing the order of addresses in the new header. The
  in and out parameters can point to the same buffer.

  The function sets the ip60r_segleft member in the ip6_rthdr0 structure to
  the number of segments (addresses) in the new header. The ip6_rthdr0
  structure is defined in netinet/ip6.h.


RETURN VALUES

  Upon successful completion, the inet6_rth_reverse() function returns 0
  (zero). Upon failure, it returns a -1.


SEE ALSO

  Functions: inet6_rth_add(3), inet6_rth_getaddr(3), inet6_rth_init(3),
  inet6_rth_segments(3), inet6_rth_space(3).
