[fpc-pascal] fpbind ipv6 version

[Alexander Grotewohl]

I sent this direct to him on accident but I don't think it worked 
anyways (bounced?)

Just some test code so not very pretty. It works, but IN6ADDR_ANY was 
missing and I'm not familiar enough with ipv6 to know how it might be 
defined in other languages.

uses sockets;
const
     IN6ADDR_ANY: array[0..3] of longint = (0, 0, 0, 0);
     test: string = 'derp derp derp'#13#10;

var
     servsoc: longint;
     clientsoc: longint;
     serv, client: TInetSockAddr6;

     i, res: longint;
begin
     servsoc:=fpsocket(AF_INET6, SOCK_STREAM, 0);

     fillchar(serv, sizeof(serv), 0);
     serv.sin6_family:=AF_INET6;
     serv.sin6_port:=htons(1234);
     serv.sin6_addr.s6_addr32:=IN6ADDR_ANY;

     fpbind(servsoc, @serv, sizeof(serv));

     if (fplisten(servsoc, 10) < 0) then
         writeln('ow');

     i:=sizeof(client);
     clientsoc:=fpaccept(servsoc, @client, @i);
     if (clientsoc = -1) then
         writeln('ow');
     res:=fpsend(clientsoc, @test[1], length(test), 0);
     if (res = -1) then
         writeln('ow')
     else
         writeln(res);
     closesocket(clientsoc);
     closesocket(servsoc);
end.
