Hi,

I have implement tcp client/server programming which is synchronous i.e. when a request come, it serves that request the goes to others request. Now I want to incorporate a feature that will make my program asynchronous.. i.e., when a request from client is served.. then server goes to listen mode to accept another connection from client...

pls help me as soon as possible..

Hi,
  Richard Stevens book contains a very good description on that subject. Please consider buying one if you are into network programming.

1) use select and poll
2) use O_NONBLOCK on socket descriptors.

download sample codes for Stevens book from here
http://www.kohala.com/start/unpv12e.html

it is unv12e.tar.gz

unzip and see the advio folder for asynchronous io codes.

You can ask if you don't understand anything.

As network programming is based on 2 concepts : connection oriented TCP or connection less UDP

So the server can be concurent or iterative. The protocol that you use it's up to you to implement. So you can create a heap or a list based on priority.
