typedef enum { ... } SilcClientMonitorStatus;

    File transmission session status types.  These will indicate

    monitor callback.

    The SILC_CLIENT_FILE_MONITOR_DISCONNECT will be called if remote
    disconnects the session connection.  The silc_client_file_close must
    be called when this status is received.  The session is over when
    this is received.

    occured.  The SilcClientFileError will indicate more detailed error
    condition.  The silc_client_file_close must be called when this status
