Function Documentation

globus_result_t globus_xio_attr_cntl (attr, driver, GLOBUS_XIO_TCP_SET_SERVICE, const char * service_name)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Set the tcp service name to bind to. Used only on attrs for globus_xio_server_create().

Parameters:

service_name The service name to use when setting up the listener. If the service name cannot be resolved, the port (if one is set) will be used instead.

string opt: port=<string>

globus_result_t globus_xio_attr_cntl (attr, driver, GLOBUS_XIO_TCP_GET_SERVICE, char ** service_name_out)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Get the tcp service name to bind to. Parameters:

service_name_out A pointer to the service name will be stored here If none is set, NULL will be passed back. Otherwise, the name will be duplicated with strdup() and the user should call free() on it.

globus_result_t globus_xio_attr_cntl (attr, driver, GLOBUS_XIO_TCP_SET_PORT, int listener_port)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Set the tcp port number to bind to. Used only on attrs for globus_xio_server_create(). The default port number is 0 (system assigned)

Parameters:

listener_port The port number to use when setting up the listener. If the service name is also set, this will only be used if that can't be resolved.

string opt: port=<int>

globus_result_t globus_xio_attr_cntl (attr, driver, GLOBUS_XIO_TCP_GET_PORT, int * listener_port_out)

Parameters:

listener_backlog This indicates the maximum length of the system's queue of pending connections. Any connection attempts when the queue is full will fail. If backlog is equal to -1, then the system-specific maximum queue length will be used.
