Good  morning 
I  work with a small project client server (multiconnection)use(evil inside example)
Complete to have maximum connections (10) and everything go fine 
if someone from 10 clients  close the socket stay  open   
want to refresh the list   and the  clients socket .
For example if the socket number 3 close  the number 4 take the  nymber 3 possition  until number 10 go to number 9 and  stay  one  socket  open  for connections   
Iam sorry  for my english   
try to  explain  it   
have a good  night
