Hi everyone,

In TCP client programming, we use connect() to establish a new TCP connection.

connect() returns zero on success or -1 on error.

If server is up , connect() returns zero and client connects to server.

what if server is down?

I placed connect() in while loop with a condition to exit from while loop when it returns ZERO(connects successfully).

It doesn't work.........

suggest me a solution in client program to connect a server which can come UP and go DOWN at any time.
