Client recv on TCP/IP

Currently I have a blocking read on a client socket on an AIX 5.3 system on a thread.
Problem is that I have received a message to shutdown, where I need to close the client socket and perform other cleanup.  I have read that the default is blocking read. I have read the man pages and cannot see how one makes it a non-blocking read.  What is the "common" way to manage this kind of problem?  Does one make the read blocking with a wait timeout? Cannot see in IBM manuals how one does this.  Thanks in advance.

non-blocking io is done by using a setsockopt call O_NONBLK, then waiting in a select() for one of several filedescriptors and/or a timer
and when select indicates one of your descriptors is ready [ this is communicated using bitmaps ]  you can read/write that descriptor.

This mostly used when non-threaded code is used to implement f.e. a server handling several connections.  [ it predates threading / coroutines  as a way to have some parallelism.

You are using threading, why not just close the socket  and/or kill the thread?
Another thread can handle the shutdown...
