Error Types – Enumerationsenum globus_xio_udp_error_type_t { GLOBUS_XIO_UDP_ERROR_NO_ADDRS, GLOBUS_XIO_UDP_ERROR_SHORT_WRITE } Detailed DescriptionThe UDP driver is very close to the system code, so most errors reported by it are converted from the system errno. A few of the exceptions are GLOBUS_XIO_ERROR_COMMAND, GLOBUS_XIO_ERROR_CONTACT_STRING, GLOBUS_XIO_ERROR_CANCELED, GLOBUS_XIO_UDP_ERROR_NO_ADDRS, and GLOBUS_XIO_UDP_ERROR_SHORT_WRITE See Also: globus_xio_driver_error_match() globus_error_errno_match()Enumeration Type Documentationenum globus_xio_udp_error_type_tUDP driver specific error types…

Reading/Writing – globus_xio_register_read() semantics: If the waitforbytes parameter is greater than zero, the read 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 of the buffer is > 0 the read happens synchronously….
Opening/Closing – An XIO handle with the udp driver can be created with globus_xio_handle_create(). 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…
