Dear Haskell Community,
Two questions:
1) Where are the Berkeley Sockets Library functions actually
defined? I.e in which file?? Can Hugs use this??
2) In the above 1), obviously this uses green card for foreign
language calls?

Does anybody know of a simple GHC Socket sample? I want to retrieve an
HTTP URL, but I keep getting errors like this:

A minimal program that exhibits the problem is below. I am using GHC
5.02 on Win XP Pro. When I ente
Hello,
I have seen that there are several Haskell libraries
for cgi scripts and the like. Is there also a possibiliy

Hi,
I'm not sure if this is what you're asking for, but GHC comes with a

the ghc Sockets module (-syslib net) is/was broken in 5.02
it works with 5.00.2 (I did not check the more recent versions.)
a minimal example using sockets is a the bottom of this page:

e, your application _only_ needs to read from the
standard input and write into the standard output. An interactive
(that is, not a single request-single reply) daemon should also be
able to flush the standard output or set it to an unbuffered/line
buffered discipline. The application needs

Hi,
I'm happy to announce the first release of secure-sockets, a library which
aims to simplify the task of communicating securely between two
authenticated peers.
