void silc_client_run_one(SilcClient client);

    Runs the client and returns immeadiately. This function is used when
    the SILC Client object indicated by the `client' is run under some
    other scheduler, or event loop or main loop.  On GUI applications,
    for example this may be desired to used to run the client under the
    GUI application's main loop.  Typically the GUI application would
    register an idle task that calls this function multiple times in
    a second to quickly process the SILC specific data.
