nng_listener is a handle to a listener object, which is responsible for
nng_pipe objects by accepting incoming connections.
A given listener object may create many pipes at the same time, much like an
HTTP server can have many connections to multiple clients simultaneously.
|The client/server relationship described by dialer/listener is completely orthogonal to any similar relationship in the protocols. For example, a rep socket may use a dialer to connect to a listener on an req socket. This orthogonality can lead to innovative solutions to otherwise challenging communications problems.|
Listener objects may be destroyed by the
They are also closed when their associated socket is closed.
A listener may be initialized using the macro
before it is opened, to prevent confusion with valid open listener.
