At some point someone must have had that same idea .... It looks to me like these functions were part of an original attempt at IPv6 support that was abandoned long ago. They are not part of TI-RPC, but as you observed, they are merely IPv6 versions of the legacy RPC API. I don't see these implemented in glibc, for example. For IPv6 support, use functions that are part of the modern libtirpc API. This is described in Sun doc 816-1435. You probably will be most successful with the "simplified interface" which is described in Chapter 4. You might need somewhat more extensive surgery since I'm guessing you have separate code paths to invoke the IPv4 and IPv6 legacy RPC functions; generally speaking that should not be needed when using the libtirpc API. > >> >>> >>> steved >>> >>>> >>>>> Signed-off-by: Steve Dickson <steved@xxxxxxxxxx> >>>>> --- >>>>> src/rpc_soc.c | 4 ++-- >>>>> 1 files changed, 2 insertions(+), 2 deletions(-) >>>>> >>>>> diff --git a/src/rpc_soc.c b/src/rpc_soc.c >>>>> index c678429..584ac71 100644 >>>>> --- a/src/rpc_soc.c >>>>> +++ b/src/rpc_soc.c >>>>> @@ -236,7 +236,7 @@ clnttcp_create(raddr, prog, vers, sockp, sendsz, recvsz) >>>>> >>>>> /* IPv6 version of clnt*_*create */ >>>>> >>>>> -#ifdef INET6_NOT_USED >>>>> +#ifdef INET6 >>>>> >>>>> CLIENT * >>>>> clntudp6_bufcreate(raddr, prog, vers, wait, sockp, sendsz, recvsz) >>>>> @@ -392,7 +392,7 @@ svcraw_create() >>>>> >>>>> >>>>> /* IPV6 version */ >>>>> -#ifdef INET6_NOT_USED >>>>> +#ifdef INET6 >>>>> SVCXPRT * >>>>> svcudp6_bufcreate(fd, sendsz, recvsz) >>>>> int fd; >>>>> -- >>>>> 1.7.6 >>>>> >>>>> >>>>> ------------------------------------------------------------------------------ >>>>> Magic Quadrant for Content-Aware Data Loss Prevention >>>>> Research study explores the data loss prevention market.
