UDP datagrams may be lost or +delivered in duplicates or out of sequence. + +:ref:`PR_NewUDPSocket` creates a new UDP socket. The socket may be bound to +a well-known port number with :ref:`PR_Bind`. Datagrams can be sent with +:ref:`PR_SendTo` and received with :ref:`PR_RecvFrom`. When the socket is no +longer needed, it should be closed with a call to :ref:`PR_Close`. + + +See Also +-------- + +:ref:`PR_NewUDPSocket` is deprecated because it is hardcoded to create an +IPv4 UDP socket. New code should use :ref:`PR_OpenUDPSocket` instead, which +allows the address family (IPv4 or IPv6) of the new UDP socket to be +specified. |
