Parrot fetched its first web page tonight. Its a baby step, but hey... :)

You can now stuff hostnames into a socket as well as a numeric IP address.

see examples/io/http.imc

Can we do IPv6?

(Not meant to be a throw away question. As I understand it many hostname
functions were changed or tweaked for IPv6, and coping with it now is
better than retrofitting it later)

I forgot to say:

Hey, cool! Nice work.

Today web pages, tomorrow self propagating worms? Muahahahaha

Sorry for delay on response, just got to my email.

Yes, I intend to encapsulate IPv4 and IPv6 in the same API.

Some of the changes are pretty simple (like instead of using inet_addr, use
inet_aton, etc.) while I'll not sure about the rest. It's been a while
since I did any socket projects but its all coming back pretty fast. :)

Luckily I have a very nice C++ library that I wrote over the past few years
so a lot of it will be cut and paste and a little rework.

Speaking of which, (this version of) Solaris needs -lresolv to use inet_aton;
uname -a:

SunOS foobar 5.8 Generic_108528-10 sun4u sparc SUNW,Ultra-4

The error:

cc -o parrot -L/opt/SUNWspro/WS6/lib -g imcc/main.o blib/lib/libparrot.a
-lsocket -lnsl -ldl -lm
ild: the archive blib/lib/libparrot.a has entries with the same name --
consistency checks during incremental links are not possible for these
entries
ild: (undefined symbol) inet_aton -- referenced in the text segment of
blib/lib/libparrot.a(io_unix.o)
*** Error code 5
make: Fatal error: Command failed for target `parrot'

No error if I manually add -lresolv to C_LIBS in the Makefile.

Thanks for the report. I'll patch it. Time for be to get my old Sun box out of
the closet.
