Subject: how to free a Socket
Message-Id: <374037D9.DEADE304@elfi2.rz.ruhr-uni-bochum.de>
I am using IO::Socket and IO::Select for a server-application. Now
obviously a used socket is not freed immediately, because after a
control-d and a restart of the server-app the handle for the socket is
not valid -- I get this error:
Can't use an undefined value as a symbol reference at
/usr/local/lib/perl5/5.00502/sun4-solaris/IO/Select.pm line 57, <> chunk
1.
Now after a certain period of time (always changing!) I am able to
restart the program, which indicates the blocked socket is freed by the
system (Solaris 7 on an Unltra Sparc).
How can I get control over the freeing of a once used socket?
Could anyone point me into the right direction?
regards
-Sebastian-

MacPerl has some API hooks and GUI functionality, but if you want to build
full-blown, distributable apps, use something else. For one thing,
anything you write in MacPerl is going to need a perl interpreter (i.e.,
MacPerl) to run, so you can't really build stand-alone apps.
What it's good for is writing quick-and-dirty data processing scripts
where it's too much for AppleScript and too little for C or C++ and you
don't care much about a GUI. There's lots of modules for stuff like
AppleEvents and OpenTransport, etc., so it's plenty robust, but I wouldn't
wnant to write a game or word processor in it (or any other perl
platform).

Well, after 6 months, here's the answer to the quiz: what do we do about
comp.lang.perl.moderated. Answer: nothing.

]Subject: comp.lang.perl.moderated available via e-mail
]
]It is possible to subscribe to comp.lang.perl.moderated as a mailing list.
]To do so, send mail to majordomo@eyrie.org with "subscribe clpm" in the
]body. Majordomo will then send you instructions on how to confirm your
]subscription. This is provided as a general service for those people who
]cannot receive the newsgroup for whatever reason or who just prefer to
]receive messages via e-mail.
The Perl-Users Digest is a retransmission of the USENET newsgroup
comp.lang.perl.misc. For subscription or unsubscription requests, send
the single line:
subscribe perl-users
or:
unsubscribe perl-users
to almanac@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.misc (and this Digest), send your
article to perl-users@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.announce, send your article to
clpa@perl.com.
To request back copies (available for a week or so), send your request
to almanac@ruby.oce.orst.edu with the command "send perl-users x.y",
where x is the volume number and y is the issue number.
The Meta-FAQ, an article containing information about the FAQ, is
available by requesting "send perl-users meta-faq". The real FAQ, as it
appeared last in the newsgroup, can be retrieved with the request "send
perl-users FAQ". Due to their sizes, neither the Meta-FAQ nor the FAQ
are included in the digest.
The "mini-FAQ", which is an updated version of the Meta-FAQ, is
available by requesting "send perl-users mini-faq". It appears twice
weekly in the group, but is not distributed in the digest.
For other requests pertaining to the digest, send mail to
perl-users-request@ruby.oce.orst.edu. Do not waste your time or mine
sending perl questions to the -request address, I don't have time to
answer them even if I did know the answer.
