.SH NAME
globus_xio_udp_driver_instance \- Opening/ClosingAn XIO handle with the udp driver can be created with \fBglobus_xio_handle_create()\fP\&.
.PP
The handle can be created in two modes: open server or connected client\&. If the contact string does not have a host and port, the udp socket will accept messages from any sender\&. If a host and port is specified, the udp socket will be 'connected' immediately to that host:port\&. This blocks packets from any sender other than the contact string\&. A handle that starts out as an open server can later be 'connected' with \fBGLOBUS_XIO_UDP_CONNECT\fP (presumably after the first message is received from a sender and his contact info is available)\&.
.PP
When the XIO handle is closed, the udp driver will destroy its internal resources and close the socket (unless this socket was set on the attr to \fBglobus_xio_register_open()\fP)\&.
