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

Yes, you should close and go back to step 1:

close() closes a file descriptor, so that it no longer refers to any file and may be reused.

From here.
