Shutdown the full-duplex connection on socket so in the manner of how:
- shut/rd
- disallow further receiving
- shut/wr
- disallow further sending
- shut/rdwr
- disallow further receiving and sending
The system normally shuts down the connection itself when closing, so calling this manually is not often necessary. One usage example is using shut/wr to inform a server you have finished transmitting, while allowing it to continue sending to you.
