I would like to create a simple example TCP server in C. It should be able to receive multiple client connections and to send a string to each of them separately, before closing the connection.

Many code samples like this one use a while(1) loop to keep listening for incoming client connections. Even in Richard Stevens – Unix Network Programming, Volume 1, Third Edition, Section 5.2, Figure 5.2 it is used for ( ; ; ), so almost the same.

This is probably the simplest solution, but is it correct from the programmer’s perspective? Aren’t such loops somewhat discouraged?

As an alternative, at least a SIGKILL could be catched instead and used as a condition for while, instead of 1. However, this is somewhat not the first advice in the answers to this question.

The actual question: is there any solution other than while(1) in this case? Is there a standard one, or does it depend on the specific program? In my case, I would like to keep it as simple as possible, but I would also like to avoid while(1).
