Re: Client to connect to a chat server

Hi everybody,
I have a program server that receive strings from many clients and
then send this strings to all the clients connected to him. I connect
to the server with Telnet.
But if I want to write the program client I have a problem. I have to
write code that read from keyboard a string and a code that read
strings from the server (other clients), in this way a made a chat.
But if I write this, the program stops when he has to read from the
stdandard input (keyboard) and if there are data from the server he
don't go receive them.
Also if I write code that receive data from the server, if data isn't
there, I'm wasting my time.

How can I resolve this?
Thank you very much.

What you are looking for is "select" and "non-blocking sockets". Go here: http://linoleum.leapster.org and under "network programming" you will find some examples how to use it.
Hint: when you read from the console, you read from a default file-descriptor called "stdin". You can use "select" with any file descriptor (sockets are "descriptors", too).
