/*!
Assigns a name to an unnamed socket. The name is the host address
\a address and the port number \a port. If the operation succeeds,
bind() returns true; otherwise it returns false without changing
what port() and address() return.
bind() is used by servers for setting up incoming connections.
Call bind() before listen().
