  sending recv() data to a file         


Author: arnuld
Date: Jul 17, 2008 21:35

I am creating a server which recv()s the data from the client and send()s
it to a file. The basic design idea is to have a log-server which writes a
file after receiving log information from the clients.

WANTED:

It should work like syslog in Linux:

1.) It will read data from client and creates a new file say "mylog.log"

2.) It will check if a file of same name "mylog.log" already exists and if
its size if less than say 100 KB.

(a) If the size of file is less than 100KB then server will append the
data to that file.

(b)If the size of the file is equal to 100KB then server will create a
new file with same name "mylog.log" after moving the old file to name
like "mylog.log.0" or "mylog.log.5" etc.

(c) if the size of file is less than 100 KB and writing data to file
makes it larger than 100 KB, then server should create a new file.

3.) if the total number of files increase by 10, then server should delete
the oldest file which will be "mylog.log.10"

In a detail mail header, I found information similar to this:

Delivered-To: user:X.com@Y.com

In fact, the email address used to send and receive emails is:

user@X.com

What does the format in the above ``Delivered-To:'' line mean? Thank
you for your time.

  File Status programatically

Hello all, I am new here.
I have a question, how can you tell if a file has an opened handle (or
is already in use) by a process. I want to do it without having to
write a device driver, or something fancy.

Thanks.

  Question on ACE 's alternative and distributed computing?         


Author: Terry
Date: Jul 17, 2008 02:58

Hi, everyone,
Do any of you have experiences in the Adaptive Communication
Environment(ACE)? It is an OO framework that implement some core
patterns in communication software. It has a C++ wrapper layer for a
bunch of POSIX C interfaces. It's designed to write higher level
middleware and distributed component efficiently. It also offers a CORBA
implementation based on its patterns and wrappers.

My question is:
Is ACE the right start if I want to learn to design and implement
distributed computing system? The ACE framework seems quite
self-contained, but I don't sense its popularity in developers and
industry. Are there any other frameworks I should turn to?

And what's your opinion about distributed system design and implementation?

Thank you!
