[Caml-list] closing sockets

[Caml-list] closing sockets

Hi all,

I've been playing around with developing a network app in ocaml and came
across an annoying 'misunderstaning' of the documentation.  Namely,
'shutdown_connection' does not clean up after 'open_connection'.  While
the socket is shutdown, the file descriptor is not closed and thus must
be done so explicitly, else you can quickly run out of file
descriptors... :(

It seems that it would be more intuitive(as a high level networking
function) if shutdown_con also closed the socket, effectively undoing
the allocations of open_con.  In fact, the networking example in this
book[1] does not do this, which is how I erred in the first place. 

I'm not networking/socket expert, so, is there any reason for this not
to occur?  The only problem I see is that making the change would break
any program that correctly closes the socket on its own...

thanks,

For sockets, "shutdown" and "close" are two different things. Have a
look at a book like Steven's UNIX Network Programming for details.
