The SOCKET g_SocketList [10000].//maximum support 10000 connections 

The main thread: 
While (true) 
{
. 
Accept () 
. 
} 

Thread 1: the select () 1 ~ 3000 connection 
Thread 2: connect the select () 3001 ~ 6000 
Thread 3: select (6001 ~ 9000) connection 
Thread 4: select (9001 ~ 10000) connection 

Above is the pseudo code,
I have been using IOCP previously, but I can't do concurrent processing different connection, so recently learned under the select, the also don't know much about, excuse me, can I this design?
