+// This is our "public" TCP API.  This allows applications to access
+// basic TCP functions, using our AIO framework.  Most applications will
+// not need this.
+
+// We treat nng_tcp as nni_tcp_conn, nng_tcp_dialer as nni_tcp_dialer,
+// and nng_tcp_listener as nni_tcp_listener.  We cast through void to
+// provide isolation of the names in a way that makes the compiler happy.
+// It turns out we can pretty much just wrap the platform API for TCP that
+// we have already created.
