Further information can be obtained + by calling :ref:`PR_GetError`. + + +Description +----------- + +When a new socket is created, it has no address bound to it. :ref:`PR_Bind` +assigns the specified address (also known as name) to the socket. If you +do not care about the exact IP address assigned to the socket, set the +``inet.ip`` field of :ref:`PRNetAddr` to :ref:`PR_htonl`\ (``PR_INADDR_ANY``). +If you do not care about the TCP/UDP port assigned to the socket, set +the ``inet.port`` field of :ref:`PRNetAddr` to 0. + +Note that if :ref:`PR_Connect` is invoked on a socket that is not bound, it +implicitly binds an arbitrary address the socket. + +Call :ref:`PR_GetSockName` to obtain the address (name) bound to a socket. |
