- Examine the error code from the screen saver and act accordingly.
0 success EAGAIN try again later other don't call this screen saver again - Test flags consistently to examine the status of the screen saver. scrn_blanked: the screen saver is running scp->status & SAVER_RUNNING: the saver is running in this vty - Correctlyu preserve status flag bits in set/restore_scrn_saver_mdoe().
