Env Variables – The udp driver uses the following environment variables • GLOBUS_HOSTNAME Used when setting the hostname in the contact string • GLOBUS_UDP_PORT_RANGE Used to restrict the port the udp socket binds to • GLOBUS_XIO_SYSTEM_DEBUG Available if using a debug build. See globus_debug.h for format. The UDP driver uses globus_xio_system (along with the File…

Server – globus_xio_server_create() causes a tcp listener socket to be created and listened upon. globus_xio_server_register_accept() performs an asynchronous accept(). globus_xio_server_register_close() cleans up the internal resources associated with the tcp server and calls close() on the listener socket (unless the socket was set on the server via the attr) All accepted handles inherit all tcp specific…

Reading/Writing – Both the globus_xio_register_read() and globus_xio_register_write() calls follow similar semantics as described below. If the waitforbytes parameter is greater than zero, the io will happen asynchronously and be completed when at least waitforbytes has been read/written. If the waitforbytes parameter is equal to zero, one of the following alternative behaviors occur: If the length…

Opening/Closing – An XIO handle with the tcp driver can be created with either globus_xio_handle_create() or globus_xio_server_register_accept(). If the handle is created with globus_xio_server_register_accept(), the globus_xio_register_open() call does nothing more than initialize the internal handle with the accepted socket. If the handle is created with globus_xio_handle_create(), and there is no handle set on the attr…

Env Variables – The tcp driver uses the following environment variables • GLOBUS_HOSTNAME Used when setting the hostname in the contact string • GLOBUS_TCP_PORT_RANGE Used to restrict anonymous listener ports ex: GLOBUS_TCP_PORT_RANGE=4000,4100 • GLOBUS_TCP_PORT_RANGE_STATE_FILE Used in conjunction with GLOBUS_TCP_PORT_RANGE to maintain last used port among many applications making use of the same port range.
