Used on attrs for globus_xio_server_create(), globus_xio_register_open() and with
globus_xio_handle_cntl() to set the size of the send buffer used on the socket.
Parameterssndbuf The send buffer size in bytes to use. (default is system specific)
string opt: sndbuf=formattedintglobus_result_tglobus_xio_server_cntl(server,driver,GLOBUS_XIO_TCP_GET_HANDLE,globus_xio_system_socket_t*handle_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 socket handle on an attr, handle, or server.
Parametershandle_out The tcp socket will be stored here. If none is set, GLOBUS_XIO_TCP_INVALID_HANDLE will be
