Reusing socket descriptor on connection failure

Question

In my client code, I am following these steps to connect to a socket:

1. Creating a socket

   sockDesc = socket(PF_INET, SOCK_STREAM, IPPROTO_TC         
   
   
           

Answer 1

If the connection was broken and you try to write on the file descriptor you should get the broken pipe error/signal. All this is saying is that the file descriptor you tried writing to no longer has anyone on the other side to read what you are sending.

What you can do is catch the signal SIGPIPE and then deal with the reconnecting by closing the FD and going back to your step 1. You will now have a new FD you can read and write from for the connection.
